Life is 10% what happens to you and 90% how you react to it.
All things come from God and all things must return to God. I may not live to be an old man, so knowing that I want to enjoy it with friends and family and try to improve myself along the way. Why get angry or sad? That's wasted time.
I know that hope and belief are pillars of this life. Without them why would anyone want to live for tomorrow? I've learned that you got to believe in something a Creator, a person, a feeling...it doesn't matter. Just believe in something.
Make a difference and go out of your way to help someone.
Most importantly: "life is 10% what happens to you and 90% how you react to it."
