What mana based magic skills do people have IRL?

I've been reading a lot of LIT-RPG lately and it got me thinking about building a IRL version.

I've read that a simple 12 hour youtube course and a decent book, can vastly improve your knowledge on a topic.. This feels like "Grinding" to me.

But what would most people think of as magic. Here's my list.

- Understanding the stock market - Understanding cyber security - Knowing how to program

Mind you I'm bias.. So does anyone else have something that makes a person OP in the real world?
