If you really want something you’ll find a way. If you don’t you’ll find an excuse.

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.

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

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

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

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

Success is a journey, not a destination.

Each day is an opportunity to improve. Aim to be that little bit better than yesterday and better tomorrow than today.

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

Failure to prepare = preparing to fail

The greatest glory in loving lies not in never falling, but in rising every time we fall.

Start, struggle, fail, fix and learn. Repeat.

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. 

It is never too late to turn an unproductive day into a productive one.

Hope might be a good breakfast, but it makes a very poor dinner
