Hope might be a good breakfast, but it makes a very poor dinner

Don't expect to be good at maths or understand things straight away. Be patient and persistent. The most powerful warriors are patience and time.

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

Never let a dark chapter make you forget that better days are ahead of you. Your story is far from over.

The power of reflection is the most powerful skill you’ll learn.

If you can understand just one thing thoroughly, then you will understand everything.

Be strong enough to stand alone, smart enough to know when you need help, and brave enough to ask for it.

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