I deal with millions of logs every day, axing them in tiny pieces, looking at them. I try to find the little bit that can tell me there is a worm, warning me that we have an infection. Then, when I find one, I get my gear and find the source and scorch the whole thing to make sure the infection is contained. So, I hack infections out of the company.
When writing, I don't masturbate or climax, otherwise I'm losing the will to write the scene. I'm going to feel the excitement, even have some physical effects other than an erection, but I do not do anything so I keep this state of mind alive. Call it intellectual masturbation if you like, but most of the time, I don't even finish myself after writing. I still have a similar satisfaction as if I have climaxed, but generated by the story I just wrote. When writing Among the Stars, I haven't masturbated much to it, writing it was the only satisfaction I needed. It's only since I've started reviewing and submitting it that I'm actually taking the time to appreciate it physically.
