The wise person knows that no answer is also an answer

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

Dreams don't work unless you do.

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

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

Don't expect to be good at maths or understand things straight away. Be patient and persistent. The most powerful warriors are patience and time.

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

When you make a mistake, take another chance. Only when you choose not to do so do you fail.

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

Pure mathematics is in its way, the poetry of logical ideas.

The power of reflection is the most powerful skill you’ll learn.

It always seems impossible until it's done.

Time is your friend, impulse is your enemy.

Knowledge is of no value unless you put it into practice.

Everything that happens was once a dream.
