I can appreciate how you feel, Sinderos. Most of us identify ourselves in lots of ways. For example I'm a chef which is an "ego-investment job" meaning I'm a chef all the time, not just when I'm at the restaurant. If I quit my current job, who am I then? An unemployed chef? A guy that used to be a chef? Hobbies can define us, beliefs can define us, as can political parties, clubs and activities, and of course what we choose to drink.
It feels like I'm the most "me" when I'm in the woods, hiking or camping. But I think we continually refine and redefine who we are we live more life.
