Skills are built not born.

Success is a journey, not a destination.

You're not in competition with anyone but yourself. Outdo your past, not other people.

The road to success is like a staircase. If you want to succeed, double your failure rate

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

Everything you want is on the other side of fear

Tough times never last, but tough people do.

Hope might be a good breakfast, but it makes a very poor dinner

Good mathematics is not about how many answers you know... It is about how you behave when you don't know.

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

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

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

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

The journey of a thousand miles begins with one step. 

There are no shortcuts to any place worth going.
