There are no shortcuts to any place worth going.

Success is not final, failure is not fatal.  It is the courage to continue that counts.

You can pick up a mistake and carry it as a burden,  or you can set it down as use it as a stepping stone to greatness.

When you make a mistake, take another chance. Only when you choose not to do so do you fail.

It doesn’t matter where you start, it matters how you end

Knowledge is of no value unless you put it into practice.
