I think, therefore I am.

Yesterday is history, tomorrow is a mystery, but today is a gift—that's why it's called 'the present

Success is the sum of small repeated efforts, day in and day out.

Be strong enough to stand alone, smart enough to know when you need help, and brave enough to ask for it.

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

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

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.

Work on your weaknesses until they are your strengths and work on your strengths until they are second nature.

Dreams don't work unless you do.

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

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

Each day is an opportunity to improve. Aim to be that little bit better than yesterday and better tomorrow than today.

The greatest mistake we make is living in constant fear that we will make one.

Whenever you find yourself doubting how far you can go, just remember how far you have come.

You cannot start the next chapter of your life if you keep re-reading the last one.
