Yesterday is history, tomorrow is a mystery, but today is a gift—that's why it's called 'the present

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. 

Nothing is impossible if you want it badly enough. Impossible = I'm possible.

Fall down seven times, stand up eight.

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

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

Don’t confuse your path with your destination. Just because its stormy now doesn’t mean you are headed for failure.

Each day is an opportunity to improve. Aim to be that little bit better than yesterday and better tomorrow than today.

Hard work beats talent when talent doesn't work hard.

Be strong enough to stand alone, smart enough to know when you need help, and brave enough to ask for it.

Hard work always pays off - it is not a question of if you will get there, but WHEN you will get there

Shoot for the moon and even if you miss you’ll land among the stars/

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

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

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