The world owes you nothing. Stop pretending that your dissatisfaction with life is the fault of others and their inconveniences to your disposition. You have complete control over every situation in how you process information and react to the problem at hand. Be kind when you don't have to. Don't let your temper escalate when something doesn't go your way. Stop believing that everything is meant to fall into your lap.
I repeat, the world owes you nothing at all. You are here, no matter what you have already accomplished or what still lies beyond, it is your responsibility alone to realize these things. No one else will do it for you.
