In the mid-70's, I was in middle management for an international airfreight company, at their headquarters in Seattle. I was doing well, but the stress finally wore me down. I was looking for answers, what to do with myself. I loved to build things around the house, and was considering finish carpentry. So, I joined a high school Building Trades class in Vermont. They built new houses from scratch. The students worked on every facet of construction- from framing, to sheetrock, preparing cabinets from rough-stock lumber, masonry and electrical and plumbing. None of the students wanted to touch the plumbing. I volunteered. Working with one other student, we handled everything from the heating and venting system, to drainage and water lines. I was challenged, and satisfied. When the water was finally turned on at the end of the project, there were no leaks in that house. That was it. I then trained under three masters licensed plumbers for the next five years, earning my first master plumbers license in 1986. I have been happily plumbing ever since.
