Dreams don't work unless you do.

The greatest enemy to human potential is your comfort zone

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. 

99% of genius comes from hard work, the remaining 1% comes from innate talent

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

Tomorrow is worth more than yesterday but less than today.

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

Hard work always pays off - it is not a question of if you will get there, but WHEN you will get there

The bad news is time flies, the good new is that you're the pilot.

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

Just stick with it, what seems hard now will one day be your warm up.

99% of failures come from people who have the habit of making excuses.

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

Everything that happens was once a dream.

Failure is NOT your destiny. Failure is the key to success.
