Philip Roth: "Old age isn't a battle; old age is a massacre."

Everything you've gone through in your life has made you into the person you are today. Don't hate on the past or the people that have been left there. You are stronger because of all the challenges and circumstances that you've endured. Be thankful for everything because as you become stronger...life becomes easier.

Every single thing that has ever happened in your life is preparing you for the moment that is to come.

Everything in life is temporary. So if things are going good, enjoy it because it won't last forever. And if things are going bad, don't worry because it can't last forever either.
