It’s not what I wanted

I have been here about 1 month now. However, I still can’t understand lots of things here. In fact, I am an old man in the software development, and I know how to handle lots of cases. But for long time, I can’t help myself to handle lots of things yet, I am even a little afraid to do more things. I became more cautious. It’s an aweful experience for me. And I hope all the things and emotions can slip over from me. It is a begining for me , but not graceful and satisfied.
