No one really knows enough to be a pessimist.

Do you feel gloomy? Lift your eyes. Stand on your feet. Say a few words of appreciation and love to the lord. Be positive.

The greatest revolution of our generation is the discovery that human beings, by changing the inner attitudes of their minds, can change the outer aspects of their lives.

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

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