At least he is sculpting bodies to differentiate himself somehow from the others.
Swarfrat's Laws of Work: A job has four main criteria:
1) Do other people want this?
2) Can anyone do it? (Limited Entry)
3) Is it fun/rewarding?
4) Is it difficult? (Skill)
#1 should be obvious.
Things that are easy, fun, and anyone can do you generally have to stand in line and pay money for. (Ride roller coasters)
Thing that are easy, rewarding/fun, and have limited entry, have extremely fierce competition, and high burnout. (Just about any hobby that people are occasionally tempted to 'go pro'. Professional Divers, Photographers, Musicians)
Things that are difficult, but rewarding, and have limited entry generally pay very well. Lawyers. Marriage.
Things that are difficult, gruelling, and anyone can do, generally don't pay anywhere near what you'd have to pay me to do them. (Corollary - moving dirt is one of the lowest paying jobs out there, but if you've ever hired it out, you know it's incredibly expensive). Earth Moving, Marriage.
Ah... I've forgotten all the combinations now, it's early. Someday I'll write them all down. Anyway my point is that there's always going to be a flood of people trying to make a go of this, and if you want to succeed, you HAVE to DIFFERENTIATE yourself. And be willing to charge stupid high prices while simultaneously living on Ramen Noodles and frozen pizzas for a long time, while enduring endless internet criticism of people saying that you're just slapping off the shelf parts together and charging way too much for. Which IS exactly what you're doing, but you just have to figure out how to get away with it.
