There are no bad mistakes in maths, only discoveries.

Nothing is impossible if you want it badly enough. Impossible = I'm possible.

We learn more from failure than we do from success.

Just stick with it, what seems hard now will one day be your warm up.

The journey of a thousand miles begins with one step. 

Knowledge is of no value unless you put it into practice.

Instead of finding reasons why you can't, find reasons why you can.

The greatest mistake we make is living in constant fear that we will make one.

Do Not Be Afraid To Make Mistakes. Each mistake teaches us something.

In order to become better than anybody else you must first become better than yourself.

You can have results or excuses, not both

Pure mathematics is in its way, the poetry of logical ideas.

The wise person knows that no answer is also an answer

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. 

We all make mistakes. What matters is how we choose to move forwards from them.
