The biggest thing is online shopping. So that you don't have to dress up, go down Bond Street or Rodeo or wherever, go and be intimidated by shop assistants to buy Gucci shoes or a Prada dress. You can just go online and, if it doesn't fit you, send it back. And I think that is the biggest, biggest difference, because that means everybody can do it.
If you're looking for an adventure, an intellectual challenge, and a close-knit community of professionals, consider land surveying! It's not for everyone, and I'd recommend working as a surveyor's assistant or office staff before committing to the necessary schooling.
I started photography more or less by accident when I was already 27. I was taken on as an assistant by a photographer who was a friend of a friend and I very quickly understood the potential of expression in photography.
In movies, you have a production assistant carrying your chair around and getting you coffee. In theater, no one carries your chair, no one gets you your coffee, there's no craft service, there's no per diem. The only thing that is provided for you is coffee, tea, sugar and milk. It doesn't matter how big a star you are or whatever.
It's true, I do sometimes suspend myself over the canvas, but mostly I work at a table when I'm making a painting. When I use 'The Rig,' my feet are firmly anchored. I lower myself horizontally just long enough to make a brush stroke - a matter of seconds - and then I'm upright again. My assistant then erases the painting quickly with a squeegee and I go for it again... until I get it right. It's like trying to hit a home run.
