I used to put A LOT of weight on what people thought of me, and it heavily damaged my self-esteem. The key to letting go of what people think is by what others have already said, enjoying things that make YOU happy, and do things for yourself where it doesn't matter what anyone thinks, because you're not doing it for them, you're doing it for YOU.

A big part of that is also letting go of comparing yourself to others too, that has been my biggest obstacle on the road to self-discovery.
