You're not anyone's responsibility but your own.
It's part of growing up, I think.
That moment you realize it's not someone else's job to take care of you.

Nobody has to love you.
Nobody has to appreciate you.
Nobody has to care for you.

Accepting that is hard, and nearly impossible for most.
But treating others as if they owe you something, in the end - is a hell of a lot harder.

Treat everything as a gift, if not a fucking miracle.
Each smile, each lovely word or considerate gesture.

The world owe's you nothing.
Be grateful.
