After high school attended a Community College and completed an Architectural Technology Diploma program.
Worked in the industry as a designer/draftsman for a few different Architectural and Engineering firms.
Then ended up in a business partnership doing Architectural design, spec writing, drafting services and construction project management on residential, small commercial and industrial projects.
Moved onto a partnership in a larger projects firm. My partner was an Architect, I was the construction Project Manager. We designed and built Churches, Nursing Homes, Schools, Industrial/Commercial, Condo/Townhouse projects, etc. Enjoyed the business, made good money, spent good money. But I had no life. Left in the morning before my kids got up and didn't get home until after they were in bed. I don't think my marriage would have survived and my kids would have said “Daddy who?”
My partner and I then ended up in the financial industry, each running our own agencies. The last major recession pretty much decimated my business, wiping out most of my clients in the auto/tool and mold industry.
I always had a shop over the years doing all sorts of things. Designing and building my own tools, designing and building custom furniture, cabinets, etc. Occasionally taking the odd commission that benefitted the TAF. (Tool Acquisition Fund).
Didn't have the desire or energy to go back into the trenches and rebuild my financial business at this stage in life, so started taking on more commissions which morphed into “Could you redo our kitchen, bathroom, basement, add an addition”, etc.
Of course the quickest way to ruin a hobby is to turn it into a business.
“Wonder what I could do with my old bike?”
And you know the rest of that story.
Can't see any danger in ruining this hobby that way. This is an extremely rewarding hobby but certainly not a financially rewarding one.
