If you're not making mistakes, then you're not doing anything. I'm positive that a doer makes mistakes.

When you are through learning you are through.

Ten strong horses could not pull an empty baby carriage if they worked independently of each other.

As long as you try your best, you are never a failure. That is, unless you blame others.

Opponents are working very hard to defeat us. Let's not do it for them by defeating ourselves from within.

We're not all equal as far as intelligence is concerned. We're not equal as far as size. We're not all equal as far as appearance. We do not all have the same opportunities. We're not born in the same environments, but we're all absolutely equal in having the opportunity to make the most of what we have and not comparing or worrying about what others have.

How hard you work at correcting your faults reveals your character.
