You can also reinvent yourself whenever you move from a place to another. I used to live in a small and enclosed community to my twenties until I moved out into an environment I knew nobody. It gave me a clean-slate, and after returning a year later, people close to me told I had changed a lot. Moreover, I continued to be the new me. The gap in the shared history cut both ways: I could forever hide behind it and explain e.g. some opinion of mine to come from influences of that time, but on the other hand, it was also the last time someone else than I knew a coherent history of me.
Since then, I have moved into new environments four additional times. Each time I see it as a possibility to reflect what I'd like to change and work towards that. And whenever I return to home, I feel like a tourist now.
