My old boss from about a decade ago was ex-Royal Engineers and his work ethic was unreal. His thought process when going into any job was always well thought out, logical and made perfect sense.
It's kind of rubbed off on me too, if I have to go to a site I'm there sharp, having planned and prepped and made sure I've got everything I need to complete the job and I plan for if I won't finish the job or run into issues or problems when I'm there. That all sounds like common sense, but for the majority of gimps I've worked with, in various jobs over the years, it isn't. You'd be amazed how many folk would go to a job alone or with me, and be completely underprepared for it, run into issues and have to go back another day to finish it. When I worked with this guy from the Army that never happened once, nor does it ever happen to me when I'm on a solo trip.
