We all have two lives. The second begins when we realise we only have one. 

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

Go as far as you can see, when you get there, you’ll be able to see further

You can have results or excuses, not both

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

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. 

The greatest glory in loving lies not in never falling, but in rising every time we fall.

The greatest enemy to human potential is your comfort zone

Fall down seven times, stand up eight.

Hard work beats talent when talent doesn't work hard.

A book a day keeps the stupidity away.

Nobody said it’d be easy, they just promised it would be worth it.

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

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

I can is 100 times more important than IQ.
