Nothing is impossible if you want it badly enough. Impossible = I'm possible.

We learn more from failure than we do from success.

There are no shortcuts to any place worth going.

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

Dreams don't work unless you do.

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

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

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

99% of genius comes from hard work, the remaining 1% comes from innate talent

I fear not the man who has practiced 10,000 kicks once, but I fear the man who has practiced one kick 10,000 times.

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

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. 

Everything you want is on the other side of fear

Skills are built not born.

Be strong enough to stand alone, smart enough to know when you need help, and brave enough to ask for it.
