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

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

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. 

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.

Failure is not the opposite of success, it is part of the success.

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

Failure to prepare = preparing to fail

The boxer is not afraid of being knocked down, he is afraid of not being able to get up again.

The road to success is like a staircase. If you want to succeed, double your failure rate

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

Procrastination makes easy things hard and hard things harder.

Work ethic is important, because, unlike intelligence, athleticism, or charisma, or any natural attribute, it’s a choice.

There are no bad mistakes in maths, only discoveries.

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.

Skills are built not born.
