Does someone know how to make some money quick as a teenager

I really wanna learn how to design thumbnails

Google Books is profitable?

Anybody have good niche ideas for a YouTube shorts channel?

My name is Morgan, I’m a 15 year old content creator/YouTuber and high school student. I am growing my YouTube Channel called Morgan Sattia. It’s all about lifestyle vlogs and sharing my Faith. I also do instagram reels. My goal is to grow my platform on YouTube and eventually get monetized. I also want to learn how to make thumbnails and clips to sell to people.
