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

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

Don’t compare yourself to others. Compare yourself to the person you were yesterday.

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

The easiest person to deceive is yourself.

Procrastination is the thief of time and the enemy of success.

Don't fear failure, fear being in the same exact same place next year as you are now.

Everything you want is on the other side of fear

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.

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

Start, struggle, fail, fix and learn. Repeat.

Hard work always pays off - it is not a question of if you will get there, but WHEN you will get there

I can is 100 times more important than IQ.

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