“Resolve to keep happy, and your joy and you shall form an invincible host against difficulties.”

“Joy is the holy fire that keeps our purpose warm and our intelligence aglow.”

“Your success and happiness lie in you.”

“Keep your face to the sun and you will never see the shadows.”

“There is joy in self-forgetfulness. So I try to make the light in others' eyes my sun, the music in others' ears my symphony, the smile on others' lips my happiness.”

“Keep your face to the sunshine and you cannot see the shadows. It's what the sunflowers do.”

“For, after all, every one who wishes to gain true knowledge must climb the Hill Difficulty alone, and since there is no royal road to the summit, I must zigzag it in my own way. I slip back many times, I fall, I stand still, I run against the edge of hidden obstacles, I lose my temper and find it again and keep it better, I trudge on, I gain a little, I feel encouraged, I get more eager and climb higher and begin to see the widening horizon. Every struggle is a victory. One more effort and I reach the luminous cloud, the blue depths of the sky, the uplands of my desire.”
