Optimism/Pessimism

"How foolish is the pessimist, despondent and forlorn, who always when he gets a rose goes hunting for the thorn.

The optimist has better sense; the charm of life he knows. He doesn’t mind a scratch or two if he can get the rose.

So don’t be a pessimist, bogged down with discontent; the optimist has heaps of fun that doesn’t cost a cent."
