The secret of change is to focus all of your energy, not on fighting the old, but on building the new.

Anyone who has never made a mistake has never tried anything new.

Be kind, everyone you meet is fighting a hard battle.

The more I see, the less I know for sure.

Think good, and good follows. Think evil, and evil follows. You are what you think all day long.

Push harder than yesterday if you want a different tomorrow.

Success is the sum of small efforts repeated day in and day out.

Men's best successes come after their disappointments.

Early success is a terrible teacher. You’re essentially being rewarded for a lack of preparation, so when you find yourself in a situation where you must prepare, you can’t do it. You don’t know how.
