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.

Procrastination is the thief of time and the enemy of success.

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

99% of genius comes from hard work, the remaining 1% comes from innate talent

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. 

Pure mathematics is in its way, the poetry of logical ideas.

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

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

I can is 100 times more important than IQ.

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

You cannot escape the responsibility of tomorrow by evading it today

Don't be afraid to take an unfamiliar path.  Sometimes they're the ones that lead you to the best places.

Success is a journey, not a destination.

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

The journey of a thousand miles begins with one step.
