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

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

The greatest glory in loving lies not in never falling, but in rising every time we fall.

If you really want something you’ll find a way. If you don’t you’ll find an excuse.

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

Skills are built not born.

There are no bad mistakes in maths, only discoveries.

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

Good mathematics is not about how many answers you know... It is about how you behave when you don't know.

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

Failure to prepare = preparing to fail

Procrastination makes easy things hard and hard things harder.

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

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

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