Pessimism leads to weakness, optimism to power.

When you are enthusiastic about what you do, you feel this positive energy. It’s very simple.

The positive thinker see the invisible, feels the intangible, and achieve the impossible.

The less you respond to negative people, the positive your life will become.

A pessimist is a man who thinks everybody is as nasty as himself, and hates them for it.

When I examine myself and my methods of thought, I come to the conclusion that the gift of fantasy has meant more to me than my talent for absorbing positive knowledge.

Have to and get to—both are choices. One is negative and one is positive. Choose the right one and it can change your life.

The optimist sees the rose and not its thorns; the pessimist stares at the thorns, oblivious of the rose.

I don’t believe in pessimism. If something doesn’t come up the way you want, forge ahead. If you think it’s going to rain, it will.

An optimist may see a light where there is none, but why must the pessimist always run to blow it out?

To establish true self-esteem, we must concentrate on our successes and forget about the failures and the negatives in our lives.

Man is not worried by real problems so much as by his imagined anxieties about real problems.
