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

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

We learn more from failure than we do from success.

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

Everything that happens was once a dream.

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

Hard work always pays off - it is not a question of if you will get there, but WHEN you will get there

Never underestimate the importance of small steps. small steps = big changes. 

Lose an hour in the morning and you will spend all day looking for it.

The temptation to quit will be the greatest when you are about to succeed

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

There is no talent here. There is hard work and obsession. You could be anyone if you put in the time.

Don’t practice until you get it right, practice until you can’t get it wrong.

We all make mistakes. What matters is how we choose to move forwards from them.

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