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.

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. 

There are no bad mistakes in maths, only discoveries.

Your attitude is everything. Pick a good one.

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

We learn more from failure than we do from success.

99% of genius comes from hard work, the remaining 1% comes from innate talent

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

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

Everything that happens was once a dream.

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

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

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

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

You can be shown the path, but only you can make the first step.
