I’ve not ever taken life drawing classes.
I’ve worn a lot of hats professionally in my 30 years, and I will say being an artist is absolutely the most difficult profession I’ve ever undertaken. I live solely off my artwork. I have enough money to pay my bills, and that’s pretty much it. It’s very difficult. I pretty much work, in some capacity, from the time I’m awake until I go to sleep. It’s a really fun job, but it’s also all consuming. You must be on call at all times, and if you’re not you’ll easily miss opportunities.
