You are a child of the universe no less than the trees and the stars; you have a right to be here. - Max Ehrmann

Beyond a wholesome discipline, be gentle with yourself.
You are a child of the universe, no less than the trees and the stars; you have a right to be here.
And whether or not it is clear to you, no doubt the universe is unfolding as it should.

Go Placidly, Amid the noise and Haste & Remember what peace there may be in silence...

If you compare yourself to others, you may become vain and bitter; for always there will be greater and lesser persons than yourself.
