Life is good when we think it's good. Life is bad when we don't think.
Thinking good thoughts is not enough, doing good deeds is not enough, seeing others follow your good examples is enough.
Perfection is perfectly simple; fouling things up requires true skill.
Thoughts are the gun, words are the bullets, deeds are the target, the bulls-eye is heaven.
Live to learn, learn to live, then teach others.
Smile, it's better than a poke in the eye.
