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. 

I can is 100 times more important than IQ.

You'll never change your life until you change something you do daily. The secret to success and change in found in your daily routine.

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

Skills are built not born.

I have not failed, I've just found 10,000 ways that won't work.

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.

Tough times never last, but tough people do.

It doesn’t matter where you start, it matters how you end

The greatest enemy to human potential is your comfort zone

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

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

Dreams don't work unless you do.

Work on your weaknesses until they are your strengths and work on your strengths until they are second nature.

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.
