Above all, don't lie to yourself. The man who lies to himself and listens to his own lie comes to a point that he cannot distinguish the truth within him, or around him, and so loses all respect for himself and for others. And having no respect he ceases to love.

Fyodor Dostoyevsky

It's a wonderful thing to be optimistic. It keeps you healthy and it keeps you resilient.

Daniel Kahneman

Begin doing what you want to do now. We have only this moment, sparkling like a star in our hand, and melting like a snowflake.

Marie Ray

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

Helen Keller

Do you not see how necessary a world of pains and troubles is to school an intelligence and make it a soul?

John Keats

If you could kick the person in the pants responsible for most of your trouble, you wouldn't sit for a month.

Theodore Roosevelt
