Failure to prepare = preparing to fail

It is never too late to turn an unproductive day into a productive one.

Skills are built not born.

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

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

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. 

Success is not final, failure is not fatal.  It is the courage to continue that counts.

There are no bad mistakes in maths, only discoveries.

We learn more from failure than we do from success.

Work on your weaknesses until they are your strengths and work on your strengths until they are second nature.

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

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.

Go as far as you can see, when you get there, you’ll be able to see further

It always seems impossible until it's done.

You're not in competition with anyone but yourself. Outdo your past, not other people.
