There is nothing more dreadful than the habit of doubt. Doubt separates people. It is a poison that disintegrates friendships and breaks up pleasant relations. It is a thorn that irritates and hurts; it is a sword that kill.

Every person who wins in any undertaking must be willing to cut all sources of retreat.

If I can do it, you can do it. Anybody can.

As far as your self-control goes, as far goes your freedom.

Be glad of life because it gives you the chance to love, to work, to play, and to look up at the stars

I can choose either to be a victim of the world or an adventurer in search of treasure.

Wealth is like sea-water; the more we drink, the thirstier we become.
