Failure to prepare = preparing to fail

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

A book a day keeps the stupidity away.

If you can understand just one thing thoroughly, then you will understand everything.

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

The wise person knows that no answer is also an answer

There are no bad mistakes in maths, only discoveries.

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. 

Time is your friend, impulse is your enemy.

Success is the sum of small repeated efforts, day in and day out.

The bad news is time flies, the good new is that you're the pilot.

Success is not final, failure is not fatal.  It is the courage to continue that counts.

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

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

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