I have not failed, I've just found 10,000 ways that won't work.

Your limitation - its only your imagination.

Tomorrow is worth more than yesterday but less than today.

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. 

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

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

A book a day keeps the stupidity away.

Patience is when you’re supposed to get mad, but you choose to understand

Practice like you’ve never won. Perform like you’ve never lost.

We learn more from failure than we do from success.

Procrastination makes easy things hard and hard things harder.

Your attitude is everything. Pick a good one.

I had no time is no excuse. 1 hour is 4% of your day and 1 minute is 0.34 % of your day.

There are no bad mistakes in maths, only discoveries.

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