Stop giving a shit about what people think of you. This is advice most people need to hear.
There's always going to be people opposed to who you are. It's literally impossible to avoid, therefore you may as well do as you please.
I wish I’d had the courage to live a life true to myself, not the life others expected of me.
This is the most common regret for people in their deathbeds. Yet look around you and you'll see most people don't realise it until it's too late.
Don't be one of those people. The inability to do as you please will seriously inhibit your experience in life. You won't be yourself and will therefore never be truly happy.
You may think trying to fit in is fulfilling–and it is to a certain extent due to our social nature–but at the end of the day you'll always be empty.
Of course, with all things in life there's an extreme. There's social standards which make sense to follow, such as wearing clothes or following the speed limit. The point is to not let the norm dictate your life and prevent you from being who you truly are.
So instead be yourself. Find like-minded people and stop trying to fit in with people you're incompatible with. There's over 7 billion people on Earth, therefore you can basically be certain they're out there.
