Friendship and money: oil and water.

Never explain - your friends do not need it and your enemies will not believe you anyway.

I don't need a friend who changes when I change and who nods when I nod; my shadow does that much better.

I'd rather regret the things I've done than regret the things I haven't done.

A mistake is simply another way of doing things.

Winners never quit and quitters never win.

The only true wisdom is in knowing you know nothing.

A fool flatters himself, a wise man flatters the fool.

A good head and a good heart are always a formidable combination.

Do not go where the path may lead, go instead where there is no path and leave a trail.
