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. 

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

No matter how bad it gets, you’re still way ahead of those who haven’t even started.

Lose an hour in the morning and you will spend all day looking for it.

There are no shortcuts to any place worth going.

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

There is no elevator to success, you have to take the stairs.

No one starts out on top. You have to work your way up.

Your attitude is everything. Pick a good one.

Try and do one thing each day that you would really rather not do.

The boxer is not afraid of being knocked down, he is afraid of not being able to get up again.

I fear not the man who has practiced 10,000 kicks once, but I fear the man who has practiced one kick 10,000 times.

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

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

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