Rejection
It's a bit tricky when it comes to taking yourself as your own reference since you're constantly changing ; the only link between you and you previous self is your body cells, furthermore there is no physical link between you and your 7 years ago self, since all your cells would have changed , all what remains is the people you know that define who you are , oh yes and YOUR cumulative thoughts. It's even harder to make it who you are that makes the difference not who you know .
You have to know how to accept rejection and reject acceptance. Otherwise you'll step into somebody else's used shoes and live their already lived life. It's all about doing what you want , embrace rejection , it's a sign of making a difference , people will or won't like it but it's besides the point , people wouldn't want you to be better or even different .
People would like you to be just like them and will accept you , which can be either redundant or destructive , because you'll end up just like them , a dead nobody ... Take yourself as a reference and do what you want specially if you get rejected for it ...
