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

Don't be afraid to take an unfamiliar path.  Sometimes they're the ones that lead you to the best places.

We learn more from failure than we do from success.

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

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

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

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

You can have results or excuses, not both

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

Success is the sum of small repeated efforts, day in and day out.

There are no bad mistakes in maths, only discoveries.

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

The master has failed more times than the beginner has even tried

Don't fear failure, fear being in the same exact same place next year as you are now.

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