I know the picture is supposed to show Rowan Atkinson, as being funny, and he is, but by trade, he graduated with an electrical engineering background, so he is no dummy.
There will always be electricity. There will always be a need for Electrical Workers. Industrial electricians bring in pretty good money. AC&R, sometimes referred to as HVAC pays well but I would recommend getting into the industrial side of that concentration rather than finding yourself crawling up and attics or crawling under houses.
