Do something that I thought was difficult.

Not sure, but I have a theory that one could improve their self-esteem by always doing what they know is the most right/noble thing to do. in other words always knowing your intentions are worthy.. then there's nothing that anyone else can have on you, others' animosity toward you has to be invalid and more obviously reflects only their own personal issues.

Always win and support from friends

I need someone to hammer my face into a different shape

Not in the healthiest of ways but yes!

Come to terms with your flaws

I wish I knew

If anything mine is probably too high and I need to be checked back into my place!
