“The belief that unhappiness is selfless and happiness is selfish is misguided. It's more selfless to act happy. It takes energy, generosity, and discipline to be unfailingly lighthearted, yet everyone takes the happy person for granted. No one is careful of his feelings or tries to keep his spirits high. He seems self-sufficient; he becomes a cushion for others. And because happiness seems unforced, that person usually gets no credit.”
― Gretchen Rubin, The Happiness Project

“In the midst of winter, I found there was, within me, an invincible summer.

And that makes me happy. For it says that no matter how hard the world pushes against me, within me, there’s something stronger – something better, pushing right back.”
― Albert Camus

“Our prime purpose in this life is to help others. And if you can't help them, at least don't hurt them.”

“It is under the greatest adversity that there exists the greatest potential for doing good, both for oneself and others.”
― Dalai Lama XIV
