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

There are no bad mistakes in maths, only discoveries.

Hard work - a two way street where you get exactly what you put in.

Be strong enough to stand alone, smart enough to know when you need help, and brave enough to ask for it.

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. 

Fall down seven times, stand up eight.

Don't put off until tomorrow what you can do today. If today you have no time, it means tomorrow you'll be too tired and the next day you'll be something else.

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

The journey of a thousand miles begins with one step. 

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

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

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

Work on your weaknesses until they are your strengths and work on your strengths until they are second nature.

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.
