Dave, I just posted some of my philosophy on work in the mdf doors thread. Again, I really do enjoy all kinds of work, not just one thing or the other. For that millwork job, we processed about 1400 board feet of American poplar (bought in rough, I always mill my own stock) and for several days we were just jointing/planing then shaping and assembly etc Not "fine" furniture, but it is a good paying work and I love to see how efficiently I can move that stuff through the shop. Similarly for other work. Some days I might be cutting up sheets on the saw, others doing finer hand work and others stuck in finishing. I guess since I grew up in this same environment, I enjoy doing the variety.
As long as I can continue to keep things going, that is what I will do. My father started the company in the early 70's and I took over in 97' at age 26. Im going to be 45 years old this year, but I am always learning new things almost every day I go to work. I think by retirement age I will probably know enough to consider myself "good" at the trade, lol. SOme days I wonder!!
