Work on your weaknesses until they are your strengths and work on your strengths until they are second nature.

There is no elevator to success, you have to take the stairs.

Never underestimate the importance of small steps. small steps = big changes. 

Don’t compare yourself to others. Compare yourself to the person you were yesterday.

It is never too late to turn an unproductive day into a productive one.

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

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. 

We learn more from failure than we do from success.

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

You can be shown the path, but only you can make the first step.

Patience is when you’re supposed to get mad, but you choose to understand

You can have results or excuses, not both

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.

Fall down seven times, stand up eight.

You're not in competition with anyone but yourself. Outdo your past, not other people.
