Optimists Need Pessimists

Optimists look for opportunities.
   Pessimists look for the worst in life.

Some people are optimists when things are involved and a pessimists when people are involved.

Optimists tend to live in the clouds, unlike pessimists who live with feet planted on the ground.

It's been said that POW's live longer as pessimists than optimists. Probably because in their mind, the pessimists has faced the worst.

So, to keep one balanced, mix a little dose of reality (pessimists) with dreaming, (optimists) and you'll go far.
