You cannot escape the responsibility of tomorrow by evading it today

Twenty years from now you will be more disappointed by the things you didn’t do than the things you did do

The journey of a thousand miles begins with one step. 

Success is a journey, not a destination.

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

Tough times never last, but tough people do.

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

Start, struggle, fail, fix and learn. Repeat.

It doesn’t matter where you start, it matters how you end

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

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

It is never too late to become what you might have been

No matter how bad it gets, you’re still way ahead of those who haven’t even started.

Everything you want is on the other side of fear

Failure is not the opposite of success, it is part of the success.
