There are no bad mistakes in maths, only discoveries.

If you really want something you’ll find a way. If you don’t you’ll find an excuse.

Run in the morning before your body figures out what you're doing

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

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. 

Skills are built not born.

A book a day keeps the stupidity away.

Life is full of opportunities. With every opportunity that is missed, another one is born.

Mistakes have the power to turn you into something better than you were before.

Whenever you find yourself doubting how far you can go, just remember how far you have come.

Procrastination is the thief of time and the enemy of success.

Everything that happens was once a dream.

Tough times never last, but tough people do.

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

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.
