A book a day keeps the stupidity away.

When you make a mistake, take another chance. Only when you choose not to do so do you fail.

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

Don’t compare yourself to others. Compare yourself to the person you were yesterday.

No matter how bad it gets, you’re still way ahead of those who haven’t even started.

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

There is no talent here. There is hard work and obsession. You could be anyone if you put in the time.

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

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