Pure mathematics is in its way, the poetry of logical ideas.

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

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

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

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.

We all have two lives. The second begins when we realise we only have one. 

Life is full of opportunities. With every opportunity that is missed, another one is born.

Run in the morning before your body figures out what you're doing

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

Your attitude is everything. Pick a good one.

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

We learn more from failure than we do from success.

You cannot escape the responsibility of tomorrow by evading it today

Don’t be afraid to work hard and find out how good you can really be.

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