The temptation to quit will be the greatest when you are about to succeed

Hard work - a two way street where you get exactly what you put in.

You can hire a tutor but you can't hire someone to practice for you.

Success is a journey, not a destination.

Fall down seven times, stand up eight.

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

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

The journey of a thousand miles begins with one step. 

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

Time is your friend, impulse is your enemy.

Success is the sum of small repeated efforts, day in and day out.

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. 

Everything you want is on the other side of fear

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

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