If someone betrays you once, it is his fault. If he betrays you twice, it is your fault. Blessed are those who can laugh at themselves, they will never cease to be amused. Obstacles are those frightful things you see when you take your eyes off your goals.

The secret of success is to understand the viewpoint of others.

There are two ways of making yourself stand out from the crowd. One is by having a job so big you can go home before the bell rings if you want to. The other is by finding so much to do that you must stay after the others have gone. The one who enjoys the former once took advantage of the latter.

Wealth, like happiness, is never attained when sought after directly. It comes as a by-product of providing a useful service.

There is joy in work. There is no happiness except in the realization that we have accomplished something.

Why should I clutter my mind with general information when I have men around me who can supply any knowledge I need?

Any man can learn anything he will, but no man can teach except to those who want to learn.
