They say the best way to learn something is to teach it (college, teaching)

[FrankAce]

There are several things I'm learning at my disposal. How do I find people to teach it to?

You can try social media or tutoring locations if what you are learning is academic.

Teaching it to another will show that you learned something. However, it is the student who needs to learn. The art of teaching requires that you learn what is known as the zone of proximal development.

Or create “how to” videos and post them on a YouTube channel.

Imaginary students. Yourself. Pets. (My pony has had more calculus lessons than many college students.)
