I worked in construction for 36 years as a: Hey! YOU!! Yeah, YOU!! That's right, the dumbass looking guy! (that was my starting job), then I moved on to being a carpenter, carpenter foreman, general foreman, field engineer, project engineer, project superintendent, project manager and estimator... I pretty much learned as much as I could and advanced as far as I could go, short of becoming a prinicple company owner. I was fortunate enough to be able to afford to retire in 2008.
