Masturbation = Imagination + Activity. Worry = Imagination + Negativity.

Life is how you look at it.

Happiness makes us think that life is worth living, whereas depression makes us think that life is worth leaving.

Hope and the fear of death stand in the way of suicide being the leading cause of human death.

Life has always been and will always be beautiful, regardless of how some or even all people have looked, are looking, or will look at it.

Most pessimists are blinded by darkness.

We have, not problems, but negative attitudes towards some situations (towards which some people have or would have positive attitudes).

How we look at life and how we feel shape each other.

Depression is usually the result of focusing on a negative thought or situation way more often and for way longer than usual.
