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

Tough times never last, but tough people do.

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 learn more from failure than we do from success.

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

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

Success is not final, failure is not fatal.  It is the courage to continue that counts.

Practice like you’ve never won. Perform like you’ve never lost.

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

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

There are no bad mistakes in maths, only discoveries.

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

The wise person knows that no answer is also an answer

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

Your attitude is everything. Pick a good one.
