“Happiness and freedom begin with a clear understanding of one principle: Some things are within our control, and some things are not.”
“There is only one way to happiness and that is to cease worrying about things which are beyond the power or our will.”
“The more we value things outside our control, the less control we have.”
“It is our attitude toward events, not events themselves, which we can control. Nothing is by its own nature calamitous -- even death is terrible only if we fear it.”
“We cannot choose our external circumstances, but we can always choose how we respond to them.”
“Don't seek to have events happen as you wish, but wish them to happen as they do happen, and all will be well with you.”
“Freedom is not procured by a full enjoyment of what is desired, but by controlling the desire.”
“Fate leads the willing and drags along the reluctant.”
“You have power over your mind - not outside events. Realize this, and you will find strength.”
“When something happens, the only thing in your power is your attitude toward it; you can either accept it or resent it.”
