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

I think, therefore I am.

A hero is no braver than an ordinary man, but he is braver five minutes longer.

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

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

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

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

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

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

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

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

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

Mathematics Is not a spectator sport. The only way to learn mathematics is to do mathematics.

We all have two lives. The second begins when we realise we only have one. 

You cannot escape the responsibility of tomorrow by evading it today
