I dunno. It seems both arbitrary and contradictory in its assumptions and conclusions.
All I know is that, unless we're some sort of trust fund baby, completely incurious, or some sort of brain dead, we're going to spend a lot of our lifespan working, and, at least for me, I'd like it to be something, the doing of which provides satisfaction. As far as I know, we get one spin on the planet and done.
Going into the arts wasn't the smartest financial move, but the one that I was called to from a very young age, and I have few regrets, and none on which I perseverate. Regrets are a complete waste of time, a form of narcissistic onanism, unless you're going to take action to address them, or reconcile and move on.
It's almost 60 years that I've been a working artist, both fine and commercial, and while it hasn't always been thrilling and joyous, it's been largely that way, and intellectually and sensually rewarding. I get to work with color and that's always been my fascination.
