The models on the couple of posts below are just for me and have been in gestation for years, but in the end I return to them. Why?
I guess, when you come right down to it, the most common reason by far that people become model making professionals is because they take to it well at a young age and by practice they get quick enough to make it their living. What this means is that it's a paying hobby, the ideal job. Consequently, there's no escaping it. Give it up for something else if you will. Find yourself in other circumstances for a while, or get sidelined into another interest or career path even, but you will always come back to model making, either as an intense interest or back again as a career, as I have done. And as I know many have.
I spent a while living afloat and had no space for modelmaking, so I took up painting, but as soon as I was back on dry land, I looked at an old caravan in the garden and thought, "Hmm, workshop".
When I worked abroad as a clay modeller for the prototype car industry, the other guys had never heard of me. It is a very small, close-knit industry and they couldn't understand how I could have worked in the field without their knowing me. My answer was, "because I used to do this", showing them photos of previous models I'd made for clients, miniature ones in that case and that usually ended the conversation.
In all my modelmaking life I have never been asked to make any scenic models for anybody. Odd, but that's how it is, so I have always kept scenery for me. I like to go to great detail in my scenic work, experimenting and trying new ideas and I don't think anyone would want to pay for all those hours.
I don't mind, because this feeds my addiction and that, I think, is really what it is.
