Just be smart enough to know when “enough is enough.” You can’t complain about somebody crossing the line if you fail to set the boundaries. You can’t complain about somebody wasting your time when you didn’t require them to earn it. Sometimes you just have to let go. Not everything is meant to be a “forever” kind of thing. You have to be honest with yourself even if it hurts. You can’t give people too many chances to make the same “mistakes.” Learn from it. Grow out of it. Be done with it. -RobertHillSr.
If you live long enough, you'll make mistakes. But if you learn from them, you'll be a better person. It's how you handle adversity, not how it affects you. The main thing is never quit, never quit, never quit. -William J. Clinton
That if you could acquire enough, accomplish enough, you’d never want to own or do another thing. That if you could eat or sleep enough, you’d never need more. That if enough people loved you, you’d stop needing love. -Chuck Palahniuk, Choke
I have been impressed with the urgency of doing. Knowing is not enough; we must apply. Being willing is not enough; we must do. -Leonardo da Vinci
