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

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

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

Just stick with it, what seems hard now will one day be your warm up.

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. 

We all make mistakes. What matters is how we choose to move forwards from them.

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

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

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

Knowledge is of no value unless you put it into practice.

Dreams don't work unless you do.

Whenever you find yourself doubting how far you can go, just remember how far you have come.

You can pick up a mistake and carry it as a burden,  or you can set it down as use it as a stepping stone to greatness.

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

Work like you don't need the money, dance like nobody's watching and love like you've never been hurt.
