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.

Don't expect to be good at maths or understand things straight away. Be patient and persistent. The most powerful warriors are patience and time.

The master has failed more times than the beginner has even tried

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

I have not failed, I've just found 10,000 ways that won't work.

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

The greatest enemy to human potential is your comfort zone

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

Everything you want is on the other side of fear

I had no time is no excuse. 1 hour is 4% of your day and 1 minute is 0.34 % of your day.

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

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

There are no bad mistakes in maths, only discoveries.

Instead of finding reasons why you can't, find reasons why you can.

It always seems impossible until it's done.
