Finding Your Element_ How to Discover Your Talents and Passions and Transform Your Life by Ken Robinson, Lou Aronica


People in all walks of life really do achieve their best when they find their Element.


As Confucius said, “Choose a job you love, and you will never have to work a day in your life.” Confucius had not read The Element, but it feels like he did.


These days it’s probable that you will have various jobs and even occupations during your working life. Where you start out is not likely to be where you will end up. Knowing what your Element is will give you a much better sense of direction than simply bouncing from one job to the next. Whatever your age, it’s the best way to find work that really fulfills you.


If you know what your Element is, you’re more likely to find ways to make a living at it.


When you’re in your Element, your sense of time changes. If you’re doing something that you love, an hour can feel like five minutes; if you are doing something that you do not, five minutes can feel like an hour.


Being in your Element gives you energy. Not being in it takes it from you.


You only know the outer world through your inner world. You perceive it through your physical senses and you make sense of it through the ideas, values, feelings and attitudes that make up your worldview.


 The poet Anaïs Nin once said, “I don’t see the world as it is: I see it as I am.” She meant that no one has a neutral point of view. We see the world around us from the world within us and each shapes our perspective on the other. As human beings, we do not always see the world directly; we interpret our experiences through patterns of ideas, values and beliefs. Some of these have to do with our own dispositions and some have to do with the cultures we’re part of and the times we live in. In all areas of our lives, whether and how we act is affected by how we think and feel. Your own attitudes and those of the people around you may help or hinder you in finding what your Element is and pursuing it.


Being born at all, as the Dalai Lama once said, is a miracle.


It is often said that you cannot change the past but you can change the future.


As Carl Jung puts it, “I am not what has happened to me, I am what I choose to become.”


Life is not linear, it is organic.


“The saddest thing to me,” says Dr. Brooks, “is seeing someone take the job because it pays well and then spend all that money on toys to cheer themselves up for being so miserable in their jobs. The people who are doing what they love hardly feel they’re working at all, just living.”


You gotta find that thing that you love so much that you’re gonna be the best at it. I didn’t care if I was going to be poor or rich—I was gonna do this no matter. This was what was calling me. This was what made me happy. When I was cutting pieces of wood in the basement, I really felt that there was something grabbing my hand and showing me how to do it. There was no doubt in my mind that I was going where I was supposed to be going. -- Randy Parsons


There's a lot more to be learned, and I'm going to learn all the way up to the stairway to the stars

“Like Piaf I have no regrets, Oh mercy you have to have the downers and the uppers to be a complete person”

As Joseph Campbell says, if you move in the direction of your passions, opportunities tend to appear that you couldn’t have imagined and that weren’t otherwise there.


The thing I realized was that if I didn’t take the risk of living, I was guaranteed to fail. In the law firms I was working at I could see guys who had taken that route. They’d sit around having bitter conversations about how awful their lives were. I could hit the fast-forward button and see that I was headed there. I figured if I left the practice of law, I had at least a fifty-fifty chance.

 

Chris Jordan found his Element when he decided that risking everything was better than the alternative. He stays in his Element by continuously pushing himself. It has led to a richly rewarding life, though not necessarily a comfortable one.

 

“There are a lot of anxieties that go along with this. If there’s one thing I would say to someone who wants to take the risk of doing what they love, it would be to learn to bear anxiety.” It’s the price of allowing yourself to answer the question, “What’s next?” But paying that price can lead to a completely different level of fulfillment.


Mark Frankland, for example, might never have discovered his true passion if he hadn’t suddenly found himself without a job. Mark had once written a song for his wife that included the African proverb, “Life is like eating an elephant; you need to do it one mouthful at a time.” He didn’t realize it at the time, but this lyric captured the essence of his search for his Element.

“I think that part of the process of overcoming a big hurdle,” he said to me, “is not looking at how big the problem is, but just trying to find out the next step you should take. Sometimes it’s drastic, and sometimes it’s very little. Sometimes a little thing can make massive changes to your life.”


As the old proverb says, “Don’t regret becoming old: it’s a privilege denied to many.” And it is.


When she asked her patients whether they had any regrets in their lives or if they would have done anything differently, a number of themes came up again and again. These are the most common ones:

I WISH I’D HAD THE COURAGE TO LIVE A LIFE TRUE TO MYSELF, NOT THE LIFE OTHERS EXPECTED OF ME.

This was the most common regret of all. When people realize that their life is almost over and look back on it, they often realize how many of their dreams have been unfulfilled. “Most people had not honored even a half of their dreams and had to die knowing that it was due to choices they had made, or not made.”


Mark Twain used the same metaphor. Reflecting on his own life and achievements he had this advice: “Twenty years from now you will be more disappointed by the things that you didn’t do than by the ones you did do. So throw off the bowlines. Sail away from the safe harbor. Catch the trade winds in your sails. Explore. Dream. Discover.”


“Risk” is a short poem often attributed to the writer Anais Nin. It uses a powerful, organic metaphor to contrast the risks of suppressing your potential with the rewards of releasing it:

And then the day came,

when the risk

to remain tight

in a bud

was more painful

than the risk

it took

to blossom.

<think>好的,我现在要解决用户提到的粒子模拟错误:“Failed finding new element”对于粒子7在元素3中的位置(3.5, -2.6)和时间步长4159的问题。首先,我需要了解这个错误通常发生在什么情况下。根据我的知识,这种错误通常与粒子在网格中无法找到其所在的父元素有关,可能由多种因素引起。 首先,用户提到的位置坐标看起来是浮点数,可能是在仿真过程中粒子移动到了当前网格元素之外的位置。我需要考虑网格是否足够精细,或者粒子是否因为速度过大而超出了相邻元素的搜索范围。例如,在流体动力学模拟中,时间步长设置过大可能导致粒子在单个时间步内移动过远,从而无法找到新的元素。这时候可能需要调整时间步长或检查粒子速度的数值稳定性。 其次,元素3可能存在网格变形的问题,特别是在大变形或高应变的区域。如果元素发生了严重扭曲或反转,可能导致粒子坐标映射失败。这时候需要检查该元素在时间步长4159时的几何形状,确认是否有畸变或负体积的情况出现。可能需要使用更稳健的搜索算法,或者对网格进行局部细化。 另外,数值精度问题也可能导致搜索失败。例如,坐标计算时的舍入误差可能使粒子位置稍微偏离实际元素边界。这时候可以考虑增加搜索容差(tolerance)或者检查坐标计算的精度设置,比如使用双精度浮点数代替单精度。 还有可能是网格拓扑结构在仿真过程中发生了变化,比如在自适应网格细化(AMR)中,元素可能被合并或分割。此时需要确认在时间步长4159附近是否有网格操作,并确保粒子跟踪算法与网格变化同步。 用户提供的引用内容中提到了ROS环境下的机器人导航和地图构建,可能与当前的粒子模拟错误关联不大,但或许用户是在某个物理仿真环境中运行粒子模拟,比如Gazebo。如果是这样,可能需要检查仿真环境中的碰撞检测或传感器数据是否干扰了粒子位置的计算。不过,通常粒子模拟错误更直接与数值方法和网格处理相关。 接下来,我需要整理解决方案步骤。首先建议用户检查该时间步长下的网格状态,确认元素3是否存在变形或破坏。然后,验证粒子的移动是否合理,是否存在异常速度或加速度。此外,调整搜索算法参数,如增加邻近元素的搜索范围或调整容差,可能有助于定位问题。如果问题持续,可能需要启用更详细的日志记录或调试工具来捕获错误发生时的具体数据。 最后,生成相关问题,帮助用户进一步排查可能的其他原因,比如时间步长设置、边界条件或接触算法的问题。</think>### 粒子模拟错误解决方案 粒子在模拟过程中出现 `Failed finding new element` 错误,通常是由于粒子无法在指定位置映射到对应的网格元素。以下是分步解决方案: 1. **检查网格与粒子位置关系** - 在时间步长4159时,确认元素3的几何形状是否因大变形导致粒子位置$(3.5, -2.6)$超出其边界。 - 使用调试工具输出元素3的节点坐标,验证其是否发生畸变或体积反转(负雅可比行列式)。 2. **调整搜索算法参数** - 增大邻近元素搜索范围:某些求解器允许设置搜索半径(如`search_radius`参数),扩展至相邻元素以覆盖粒子可能的位移。 - 提高数值精度容差:若因浮点误差导致位置映射失败,调整容差值(例如从$1e-6$改为$1e-5$)[^1]。 3. **验证时间步长与粒子运动** - 计算粒子在步长4158至4159间的位移$\Delta x$,若$\Delta x$超过元素尺寸的50%,需减小时间步长或启用亚循环(sub-cycling)策略。 - 检查粒子速度场是否异常,例如在接触边界或高梯度区域出现数值不稳定。 4. **启用回溯机制(Backtracking)** - 若使用拉格朗日粒子追踪,可在错误发生时回退到步长4158,以更小的时间步长重新积分,并记录路径。 5. **网格适应性改进** - 在易发生大变形的区域(如元素3附近)启用局部网格细化或重划分(remeshing)。 - 示例代码(伪代码): ```python if element_distortion > threshold: remesh_local_region(element_id=3) ``` 6. **调试与日志分析** - 输出粒子7的运动轨迹和元素3的拓扑变化历史: ```bash # 在仿真日志中启用详细调试模式 set_particle_debug(particle_id=7, level=2) log_element_history(element_id=3) ``` ---
