He who has begun his task is half-way done. Have the courage to begin!

You can have results or excuses, not both

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

It always seems impossible until it's done.

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

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

You cannot start the next chapter of your life if you keep re-reading the last one.

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

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. 

There is great wisdom in being able to realise that you don’t understand something before it goes too far.

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

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

If you want to succeed, double your failure rate.

Practice like you’ve never won. Perform like you’ve never lost.
