I'm an aggressive mixture of both. I started drawing when I was old enough to hold a crayon, and took every art class I could get my hands on in school, and a few summer classes here and there through the local parks and recs district. I have had many 'how to draw X' style books throughout the years (and still have many). I majored in fine art in college, and have my degree in it. I worked at an art store for six years, which honestly taught me more about the supplies I was using than college ever did. I've even taught 'how to draw comics' classes to middle schoolers as part of a summer program a few times.
As far as my marker work goes, I'm almost 100% self-taught, meaning I figured out all of my techniques without books, tutorials, videos, or anyone telling me how to use them. I started using alcohol-based markers in high school (mid-to-late 90s), and by the time I even thought to look for tutorials about how to use them, I was already so familiar with them that I could have written most of those tutorials. I even use some techniques I've never seen anyone else talk about/use.
...all that, and I'm still disappointed with my art. I feel like I should be way better than I am.
