Not much happens during down times, and it can be rather boring. It also can be quite stressful because the money only comes after a project is completed. That doesn't always happen, however, and I must take projects when they come. Clients can sometimes be very stressful to deal with. This forces me sometimes to underbid on a project or take a project that I normally would not accept.
Clients also have trouble communicating what they want.
Then I have to fix my work to fit their rather basic and unexorbitant vision. By the time a long project is done, I'm usually quite sick of it. I can virtually recite the narrative from beginning to end, and I just don't want to sit through it anymore. Dealing with mundane business details such as bookkeeping and filing are necessary evils. I think of myself as a video person, not a business person.
