control

"We cannot choose our external circumstances, but we can always choose how we respond to them."

"You have power over your mind - not outside events. Realize this, and you will find strength."

"It's not what happens to you, but how you react to it that matters."

"Make the best use of what is in your power, and take the rest as it happens."

"Freedom is the only worthy goal in life. It is won by disregarding things that are outside our control."
