We learn more from failure than we do from success.

Mathematics Is not a spectator sport. The only way to learn mathematics is to do mathematics.

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

Don’t compare yourself to others. Compare yourself to the person you were yesterday.

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

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

It always seems impossible until it's done.

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.

1.00³⁶⁵=1 and 1.01³⁶⁵=37.7. Doing nothing at all versus small steps at a time. 

There are no bad mistakes in maths, only discoveries.

Knowledge is of no value unless you put it into practice.

Work like you don't need the money, dance like nobody's watching and love like you've never been hurt. 

Dreams don't work unless you do.

You can have results or excuses, not both

Never underestimate the importance of small steps. small steps = big changes.
