Log everything in your working time, log everything in your work: code you write, code you review, code you just saw from open source libraries.
Sometimes you could add extras: latest tech news, rss subscribed new blog entries, some thoughts or ideas that just crashed into your mind.
In such way, your working time becoming a fluent mind-flow. Yes, keep it flowing, do not stop or get stuck. There should be only small pauses, then, everything in your mind keep flowing.
