If you see the world as “people suck” it’s likely that you suck.
Try being genuinely nice.
Say hello to strangers passing by instead of looking at the ground.
Hold a door.
Give someone a compliment.
Be fucking nice & courteous.
Simple things make a huge difference.
You’ll be AMAZED what it does for your own mood!
It won’t be long before you realize it’s not the world that sucks.
