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

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. 

No one starts out on top. You have to work your way up.

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

Dreams don't work unless you do.

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

Success is a journey, not a destination.

Failure to prepare = preparing to fail

Skills are built not born.

It doesn’t matter where you start, it matters how you end

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

The journey of a thousand miles begins with one step. 

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

Time is your friend, impulse is your enemy.

Focus on progress, not perfection. Practise a little bit every day - little and often  Slow and steady wins the race.
