"Happiness" is kind of being misused here. Would I be happier if my parents decided to let me be the way I was when I was a kid? Remove all the painful little obstacles that would have IMPROVED ME AS A PERSON? Let me stay a socially awkward little urchin for the rest of my life? I probably had it ingrained in my brain, but it wasn't set in stone. You are talking about short term happiness, not long term happiness, whether it is the rest of your life, or throughout eternity.
I have had other struggles throughout my life, and it is pretty insulting to have someone tell me or somebody else to accept themselves the way they are when I worked so hard to become a better person. In other words, becoming a person that I wasn't to begin with. The purest metal is the one put through the hottest furnace.
Your identity is not determined by your personality, unless you act on those traits, either bad or good. If I acted on every single personality trait I had, I would probably be dead. I will always be autistic, but at least I'm improving as a person instead of being content with being who I was. Shouldn't we aspire to be something MORE? It is very good to have self esteem, but when it impedes personal progress, that is when it needs to STOP.
Yes, we need to love and respect other people, and help them through their hardships, but that is no excuse to impede someone else's personal progress and sense of control. Convincing someone that they are a slave to their personality, temptations, etc will handicap them for life unless someone snaps them out of it. Every spiritual son and daughter of God has great potential, and I have little respect for anyone who states otherwise. And like I said, choice is a two way street. You can either wallow in self pity and remain the same, mediocre human being you are, or you can strive to do something more and acomplish great things, despite your circumstances.
