The man who is a pessimist before 48 knows too much; if he is an optimist after it he knows too little.

When we seek to discover the best in others, we somehow bring out the best in ourselves.

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

The greatness of a man is not in how much wealth he acquires, but in his integrity and his ability to affect those around him positively.

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.

One day, in retrospect, the years of struggle will strike you as the most beautiful.

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

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

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

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

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.

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