Stretch your arms out wide and breathe the fuck in. This is your home and will be for an allotted amount of time. Don't try to change it; embrace the fact that you're somewhere at all.
Stare up at the sky if it's above you. Trace the outlines of shapes in the clouds if it's day. Look at the carpet beneath your feet if it's there. Take in your surroundings and thank someone, anyone, that this is where you are.
You must have done something to get you here. You must have done something right, something right to be alive. You must have done something to be blessed with your thoughts, your aspirations, your friends.
Don't take things for granted because one day they just won't be there. Chide a dog enough and it will run away.
The world doesn't last forever.
The world won't wait forever.
The world is not in your hands.
