Yeah, it never made sense to me either, then suddenly I'm having these thoughts. Anyway, the important part I was trying to convey is that everyone develops differently, but I think we all end up sort of the same. The ones of us who have a healthy development (people who never work and sell drugs don't for example. no professional achievements, no inclination to improve, etc) throughout life all go through a series of tests to harden us. It's natural for everyone to stop taking love-related matters so personally in order to not get hurt time and again. Likewise, as you grow, instead of being offended when people hack at you, you opt not to. Confidence is not some magic feeling that happens to special people who have it all, it's a natural result of not worrying so much about what others think about you. Being hurt/offended occasionally is a part of reality, so instead of trying to change a reality you can't change, you change your stance on reality. To me that's something that happened in a process over a lot of time though.
