Honestly the best piece of advice I can give to anyone is to stop caring what people think.
Go outside in a hoodie and jeans. Listen to that weird, obscure band. Go somewhere because you’ll have a good time, not because you think you should. Quit things that don’t make you happy. Ignore people who don’t like you. Go to sleep in public. Eat 3 muffins in a row. Brush off criticism. Cry if you have to. Go for your goals, not your parents’ goals.
We’re all self-centred and nobody cares what it is you’re doing. So prioritise your happiness and let things go from there.
