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. 

It is never too late to become what you might have been

If you fail, next time fail better.

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

Don’t practice until you get it right, practice until you can’t get it wrong.

Don’t hang your targets after you’re done shooting.

The journey of a thousand miles begins with one step.

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

Never let a dark chapter make you forget that better days are ahead of you. Your story is far from over.

The easiest person to deceive is yourself.

Your attitude is everything. Pick a good one.

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.

Yesterday is history, tomorrow is a mystery, but today is a gift—that's why it's called 'the present

You can have results or excuses, not both

There are no bad mistakes in maths, only discoveries.
