For the most skilled jester, the best gun for hire - sure. But not all mastery is rewarded with big money, much like a lot of crap sells well. Especially if you wanna bring something out from the inner world.
So if my dream is to do 10 feet tall oil painting masterpieces that would put classical artists to shame of whatever scenes I want at whatever pace I wanna paint them with no deadlines, client input, worry about expenses and no care about selling them or not selling them, what's mainstream and what others will think of it - much less setting up a business for it - if this is my dream then all I want is skills to bring those images to life, to experience that mastery come out through you with enough fuck you money to not worry about shit.
