Hard work beats talent when talent doesn't work hard.

It is never too late to turn an unproductive day into a productive one.

There is great wisdom in being able to realise that you don’t understand something before it goes too far.

Time is your friend, impulse is your enemy.

There are no bad mistakes in maths, only discoveries.

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

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. 

It always seems impossible until it's done.

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

The temptation to quit will be the greatest when you are about to succeed

Success can never happen without the journey (struggle).

Tomorrow is worth more than yesterday but less than today.
