I picked up a job doing construction, specifically windows and doors. I've always been pretty handy and know my way around the tools, but had never worked this kind of job.
Its satisfying work no doubt. I lost a ton of weight and was in the best shape i had been in years with no effort outside of work. I learned a bunch of new skills and my confidence to complete most home repairs has increased exponentially.
Downsides are the wear and tear it puts on your body. After 12 months i had more small scars than i could count, i broke my foot on my last day there. You come home filthy everyday.
For the first few weeks i was wrecked after everyday, got home and basically passed out on the lounge.
My biggest pet peeve was probably a factor of the specific company i worked at, but i found the lack of basic organization and communication infuriating. Suggestions to implement simple procedures that would reduce the number of misquotes, scheduling and general chaos are ignored because it would require change.
I'd do it again, but for a more organized and professional company.
