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

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.

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.

I have not failed, I've just found 10,000 ways that won't work.

Yesterday is history, tomorrow is a mystery, but today is a gift—that's why it's called 'the present

Tomorrow is worth more than yesterday but less than today.

You cannot escape the responsibility of tomorrow by evading it today

Success can never happen without the journey (struggle).

A hero is no braver than an ordinary man, but he is braver five minutes longer.

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.

Just stick with it, what seems hard now will one day be your warm up.

Don't be afraid to take an unfamiliar path.  Sometimes they're the ones that lead you to the best places.

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

Nothing is impossible if you want it badly enough. Impossible = I'm possible.
