We all have two lives. The second begins when we realise we only have one. 

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

Success can never happen without the journey (struggle).

It always seems impossible until it's done.

Try and do one thing each day that you would really rather not do.

Nobody said it’d be easy, they just promised it would be worth it.

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

99% of failures come from people who have the habit of making excuses.

We learn more from failure than we do from success.

Good mathematics is not about how many answers you know... It is about how you behave when you don't know.

The bad news is time flies, the good new is that you're the pilot.

In order to become better than anybody else you must first become better than yourself.

The road to success is like a staircase. If you want to succeed, double your failure rate

Start, struggle, fail, fix and learn. Repeat.

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