99% of failures come from people who have the habit of making excuses.

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. 

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

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

Fall down seven times, stand up eight.

Tough times never last, but tough people do.

Everything that happens was once a dream.

The bad news is time flies, the good new is that you're the pilot.

Shoot for the moon and even if you miss you’ll land among the stars/

A book a day keeps the stupidity away.

Be strong enough to stand alone, smart enough to know when you need help, and brave enough to ask for it.

Hope might be a good breakfast, but it makes a very poor dinner

If you want to succeed, double your failure rate.

There are no bad mistakes in maths, only discoveries.

No matter how bad it gets, you’re still way ahead of those who haven’t even started.
