Life has too many disappointments to make room for negativity.

There are two words that I believe could be completely eradicated from our vocabulary – “I can’t.” These two words are so definite that they leave absolutely no room for hope. Instead, I suggest we use the phrase, “How can I?

When accused of being an unrealistic optimist, say the sun never stops shining.

The pessimist may call the optimist a fool; but who is more foolish, the happy individual who expects more happiness or the one who fills his life with bitterness and has only more despair to look forward to?

That's my gift. I let that negativity roll off me like water off a duck's back. If it's not positive, I didn't hear it. If you can overcome that, fights are easy.

There's nothing particularly wrong with being more pessimistic than optimistic. Optimism is broad-based, non-detail-oriented thinking; pessimism is detail-oriented thinking.
