1- As a cammodel, I need to be energetic all the time. No problem, just use soda, right? Wrong. As a cammodel, I have to watch my health carefully. So a diet that's perfectly acceptable for a job like running a gas station (that's how I refer to clerks who are on second shift, since they are the only ones there and do everything to run it) is not acceptable while on camera.
2- As a cammodel, I have to stay hydrated. This is actually crucial, since my body's natural state is slightly dehydrated, and my pussy doesn't like to stay wet for long periods of time. This means I drink a hell of a lot more now. But again, it's gotta be healthy drinks. And not as much soda or coffee.
3- As a cammodel, I need a separate room. Technically, I *can* cam in the room I sleep in, and have done so, but for my mental health, it's much better for me to have a separate room. This cuts down on restless nights due to the smells associated, or due to the camera bothering me just by being in the same room.
4- As a cammodel, I use a hella lot more electricity than not. Example: my first year paying the electricity bill, it was at 120 for heating, 26 when I didn't need to run the heat all the time and didn't really need ac yet. As a cammodel, my electricity bill has never been lower than 50.
5- As a cammodel, I have to keep my camroom warm enough for me to be nude in for extended periods of time. I also have to be sure the rest of my apartment is not such a different temperature that I'm constantly sick.
While everything he listed is necessary for life, it's necessary to a bigger degree as a model. If I didn't need to stay in perfect health, I could subsist on Ramen 2 out of 3 meals a day. But since I can't afford to be low on energy, and can't afford to get sick, I have to make sure I get enough fruits, vegetables, meat, and so on. That's expensive. I could live with keeping the heat down to where I need to wear pants and a sweater all day, except my job requires me to be nude. My roommate and I would be fine in a one-bedroom apartment, but we need the extra room so we don't have to live with the smells of anal while we try to sleep. Not to mention so he can sleep while I work.
Since they are needed to a greater degree, and I wouldn't spend as much money on it if I wasn't a model, they are work expenses.
