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. 

Each day is an opportunity to improve. Aim to be that little bit better than yesterday and better tomorrow than today.

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

You can hire a tutor but you can't hire someone to practice for you.

"I" not them. Be the best version of you.

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

A book a day keeps the stupidity away.

Practice makes comfort. Expand your experiences regularly so every stretch won't feel like your first.

You can have results or excuses, not both

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

99% of failures come from people who have the habit of making excuses.

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

Success can never happen without the journey (struggle).

He who has begun his task is half-way done. Have the courage to begin!

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