Don't put off until tomorrow what you can do today. If today you have no time, it means tomorrow you'll be too tired and the next day you'll be something else.

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

Success is a journey, not a destination.

Work ethic is important, because, unlike intelligence, athleticism, or charisma, or any natural attribute, it’s a choice.

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

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

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

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

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

Everything you want is on the other side of fear

A book a day keeps the stupidity away.

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. 

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

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

I can is 100 times more important than IQ.
