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

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. 

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

You can hire a tutor but you can't hire someone to practice for you.

Procrastination makes easy things hard and hard things harder.

Mistakes have the power to turn you into something better than you were before.

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

The temptation to quit will be the greatest when you are about to succeed

Twenty years from now you will be more disappointed by the things you didn’t do than the things you did do

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

It always seems impossible until it's done.

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

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

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

A book a day keeps the stupidity away.
