Stop blaming everyone and everything else.
Yes of course sometimes the deck is unfairly stacked against you and there’s nothing wrong with fighting to correct injustice, but you can’t live in the mental state that everything wrong about your life is someone else’s fault- that’s a slippery slope and you WILL find yourself justifying self destructive behaviors eventually.
Recognize societal unfairness, but don’t let it take away your agency. If YOU can change it, change it.
