“So many things happen that we can't control, its best not to worry about what we can. Believing you can change the world has a terrible effect on one's ego.”

“Free yourself from fruitlessly worrying about things you can’t control and put your energy towards the things you can. Seize the day and take effective action on things you can change.”

“You know, there are so many things you can't control in life, like whathappens to you or how people are going to react to what you do.It's wasted energy to worry about it. But you can control how youreact. That's the trick.”

“Don't ever let anyone tell you that things can't be changed, that things can't be done. The can and they will, if we are united in what we believe.”

“The only thing a cat worries about is what's happening right now. As we tell the kittens, you can only wash one paw at a time.”

“The past is the one thing we are not prisoners of. We can do with the past exactly what we wish. What we can't do is to change its consequences.”
