Work ethic is important, because, unlike intelligence, athleticism, or charisma, or any natural attribute, it’s a choice.

Mistakes have the power to turn you into something better than you were before.

Your attitude is everything. Pick a good one.

A book a day keeps the stupidity away.

Work like you don't need the money, dance like nobody's watching and love like you've never been hurt. 

He who has begun his task is half-way done. Have the courage to begin!

If you really want something you’ll find a way. If you don’t you’ll find an excuse.

Don't expect to be good at maths or understand things straight away. Be patient and persistent. Rome wasn't built in a day, but they worked on it every single day. 

A hero is no braver than an ordinary man, but he is braver five minutes longer.

Procrastination is the thief of time and the enemy of success.

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

The easiest person to deceive is yourself.

The greatest mistake we make is living in constant fear that we will make one.

We learn more from failure than we do from success.

Success can never happen without the journey (struggle).
