Failure to prepare = preparing to fail

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

Fall down seven times, stand up eight.

Don’t hang your targets after you’re done shooting.

The easiest person to deceive is yourself.

The journey of a thousand miles begins with one step.

A book a day keeps the stupidity away.
