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

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

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

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

Everything you want is on the other side of fear

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

"I" not them. Be the best version of you.

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

The journey of a thousand miles begins with one step. 

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

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

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

It always seems impossible until it's done.

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.

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