Friedrich Nietzsche

The Christian God is the God of the sick, the God of the weak, the God of the poor.

The tree that would grow to heaven must send its roots to hell.

The higher men are distinguished from the lower by their fearlessness and their readiness to challenge the highest values.

Every talent must be paid for. One pays for it always, whether one has it or not, with a long and painful struggle.

A man who wants to do great things must know how to suffer.

The thought of suicide is a powerful comfort: it helps one through many a bad night.
