The art of being wise is knowing what to overlook.

Take time to deliberate; but when the time for action arrives, stop thinking and go in.

My number one piece of advice is: you should learn how to program.

A wise man learns by the mistakes of others, a fool by his own.

Insist on yourself. Never imitate.

Don’t treat your customers like a bunch of purses and wallets.

Don’t take too much advice. Most people who have a lot of advice to give — with a few exceptions — generalize whatever they did. Don’t over-analyze everything. I myself have been guilty of over-thinking problems. Just build things and find out if they work.

You cannot depend on your eyes when your imagination is out of focus.

The fastest way to change yourself is to hang out with people who are already the way you want to be.

Formal education will make you a living; self-education will make you a fortune.

Don't bunt. Aim out of the ballpark.

Lend your friend $20. If he doesn’t pay you back then he’s not your friend. Money well spent.

How you climb a mountain is more important than reaching the top.

Nothing will ever be attempted if all possible objections must first be overcome.
