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. 

Don't put off until tomorrow what you can do today. If today you have no time, it means tomorrow you'll be too tired and the next day you'll be something else.

The journey of a thousand miles begins with one step. 

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

You'll never change your life until you change something you do daily. The secret to success and change in found in your daily routine.

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

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

Run in the morning before your body figures out what you're doing

Tough times never last, but tough people do.

I fear not the man who has practiced 10,000 kicks once, but I fear the man who has practiced one kick 10,000 times.

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

The greatest mistake we make is living in constant fear that we will make one.

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

You cannot escape the responsibility of tomorrow by evading it today

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