Having to explain what I just read to friends gave me two amazing opportunities: to test my own understanding of a subject and to see how good I am at explaining difficult concepts to different people.

And it’s always a blessing to hear honest feedback and opinions, especially when they go against what I’ve recently come to believe and think.

Why?

Because untested opinions/beliefs will always remain true.
