Don't fear failure, fear being in the same exact same place next year as you are now.

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

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

Success is a journey, not a destination.

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

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.

Life is full of opportunities. With every opportunity that is missed, another one is born.

You can be shown the path, but only you can make the first step.

Don’t confuse your path with your destination. Just because its stormy now doesn’t mean you are headed for failure.

Everything that happens was once a dream.

Nobody said it’d be easy, they just promised it would be worth 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. 

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

Fall down seven times, stand up eight.

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