"We have every reason to be optimistic in this world. You can't, you don't build out of pessimism or cynicism. You look with optimism, work with faith, and things happen. Things will work out. Keep trying. Keep believing. Be happy. Don't get discouraged. Things will work out."
Easier said than done? Absolutely. Worth striving for? Absolutely.
P.S. Happy Father's day to my favorite Dad!
