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

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

Skills are built not born.

The greatest enemy to human potential is your comfort zone

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. 

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

Success can never happen without the journey (struggle).

It is never too late to turn an unproductive day into a productive one.

Run in the morning before your body figures out what you're doing

The easiest person to deceive is yourself.

The journey of a thousand miles begins with one step. 

Don’t hang your targets after you’re done shooting.

The gift of imperfection - let go of who you think you're supposed to be and embrace who you are.

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