Sometimes your personality just adapts to the type of work that you do.

I've expressed my introversion a lot in the last 5 years due to software development tasks. The quiet is necessary for the brain to process info even when not in front of a computer. Plus, it's not like you can share your thoughts with people, only 1 out of 10 words that come out of your mouth makes any sense to them.

I'm slowly moving to getting the product to market. I'm expecting to be a completely different person 2 years from now... Closer to what I was 10 years ago.

I understand that some people have a favorite state, but I have a hard time believing that it's a stable personality trait.
