- gratitude is very important
Not just existentially for a chance at being, but just muster as much of it as you can for the people around you, for every kindness shared with you, and for the beauty you get to experience. Even for bad shit that teaches you a lesson you can say thank you. It’s literally free.

Eckhart Tolle is a
