How did you guys learn?

I recently decided I want to be a makeup artist, wanting to go into bridal makeup (probably). Where did you guys learn? There's no license required in my state, only one school near me has a makeup specific course, but it's unavailable for now. I keep seeing these online courses but worried for possible scams and preferring in-person. I also know a lot of people online say they're self taught, but I would prefer to have at least a small course on hygienic practices and how to apply effectively and some business advice that's not just on YouTube.

My question being just....how did you guys learn? I'm the type to research the internet until it's dry, so the more information I have the better I'll feel. I appreciate whatever answers you have.
