Making myself happy vs doing the right thing

What's the difference between making myself happy and doing the right thing?

Can both correlate , so I can have the best of both worlds?

For 19 years, I've tried to fit in. To fit in with my peers' expectations of me , parents' expectations of how I should turn out and most of all, grow into the person I really am.

I spend a lot of time listening to people and their advice, trying to take it, apply it into my life and at one point I realize that you can't really use people's advice (it's not a one advice fits all) but when you pave your own way, they start judging you and how you choose to lead your life. (Even if I don't want to admit it, being judged makes me nervous).

So, at one point ,I've found (and since then, have been attempting to maintain balance between doing what I feel is right for myself and taking advice as I go (be humble, you're not that wise,Heidi).

What is the right thing? How do you actually move on from a mistake and set off to the next part of your life? I've accepted that I will always make mistakes (even if I'm afraid of mistakes) and I will embarass myself, disagree with people but trying to be somebody I'm not is way too stressful for me.

I don't particularly enjoy being a fashionista. I'm okay with my dowdy fashion.
I don't particularly enjoy a wild night out. I like having fun, going out and eating but at the end of the day, I really just want a good cup of tea and curl up with a book.
I am not interested in changing anything physically, and if anybody attempts to suggest I need cosmetic enhancement, I will shut them out.
I have problems focusing when I read sophisticated books sometimes.
I still haven't completely grasped a lot of aspects when it comes to my religion, please go easy on me, help me, cuz I'm still learning.
I am insecure about a lot of things.
I'm pretty emotional. There are things I am pretty sensitive about, but I try to be sensitive towards other people's needs too.
I have different ideas of what is good for me, and what I should do. I won't judge your choices, please allow me to make mine.

I really want to embrace myself, fully, for my flaws and good bits , ugly bits,beautiful bits. I really want to.

Ramadhan kareem, everybody. I want to embrace my imperfections while trying to improve myself, Insha Allah.
