There is no elevator to success, you have to take the stairs.

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

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

Tough times never last, but tough people do.

The journey of a thousand miles begins with one step. 

You can hire a tutor but you can't hire someone to practice for you.

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

There are no bad mistakes in maths, only discoveries.

The greatest mistake we make is living in constant fear that we will make one.

Success is the sum of small repeated efforts, day in and day out.

Skills are built not born.

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.

It doesn’t matter where you start, it matters how you end

Hard work beats talent when talent doesn't work hard.

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.
