I just generally go though life as I am and its mostly ok. I do know people though who put a huge amount of effort into moulding themselves into someone else. A girl I was at university with did this, she was kind of a tom boy though her teens when she suddenly at 19 started leaning into a this very feminine and soft persona she gave up football and getting pissed and started dressing differently and projecting this whole other persona, she seemed to change physically too becoming very pretty, beautiful even. It was like she willed herself to change. I also remember reading about Freddie Mercury, that lots of people said he couldn't sing and didn't have star quality but he willed himself into one of the best rock singers and performers of all time.
Part of me thinks that people don't really change and that who we are always comes out in the end but I wonder if people can actually change themselves dramatically, and become almost someone different?
