There are no bad mistakes in maths, only discoveries.

Skills are built not born.

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

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

There are no shortcuts to any place worth going.

The journey of a thousand miles begins with one step. 

If you fail, next time fail better.

It doesn’t matter where you start, it matters how you end

If you want to succeed, double your failure rate.

Your attitude is everything. Pick a good one.

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

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

If you can understand just one thing thoroughly, then you will understand everything.

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

Procrastination makes easy things hard and hard things harder.
