Don't fear failure, fear being in the same exact same place next year as you are now.

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

Success is not final, failure is not fatal.  It is the courage to continue that counts.

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. 

I think, therefore I am.

There is no talent here. There is hard work and obsession. You could be anyone if you put in the time.

Failure to prepare = preparing to fail

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

Shoot for the moon and even if you miss you’ll land among the stars/

Never let a dark chapter make you forget that better days are ahead of you. Your story is far from over.

Hard work beats talent when talent doesn't work hard.

Everything that happens was once a dream.

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

Your limitation - its only your imagination.

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