Work ethic is important, because, unlike intelligence, athleticism, or charisma, or any natural attribute, it’s a choice.

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

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

If you really want something you’ll find a way. If you don’t you’ll find an excuse.

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

Don't put off until tomorrow what you can do today. If today you have no time, it means tomorrow you'll be too tired and the next day you'll be something else.

You'll never change your life until you change something you do daily. The secret to success and change in found in your daily routine.

Knowledge is of no value unless you put it into practice.

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

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

Focus on progress, not perfection. Practise a little bit every day - little and often  Slow and steady wins the race.

No one starts out on top. You have to work your way up.

You cannot escape the responsibility of tomorrow by evading it today

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

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