Focus on progress, not perfection. Practise a little bit every day - little and often  Slow and steady wins the race.

The greatest enemy to human potential is your comfort zone

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

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

The gift of imperfection - let go of who you think you're supposed to be and embrace who you are.

Don’t be afraid to work hard and find out how good you can really be.

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

Success can never happen without the journey (struggle).

If you can understand just one thing thoroughly, then you will understand everything.

You can pick up a mistake and carry it as a burden,  or you can set it down as use it as a stepping stone to greatness.

Lose an hour in the morning and you will spend all day looking for it.

We are all maths people : step 1 - do maths and step 2 - be a person. 

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

There are no shortcuts to any place worth going.

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.
