Now im sort of just ranting. But this covers a whole range. From hand tools to power tools. You need to know how much gusto to use to let the tool do the work. So, regardless, not enough, the tool doesnt do much, you dont damage it depending on what it is. Too much, like say a holesaw on a drill, or a chainsaw. Your holesaw will overheat and go blunt and your drill will overheat. Same with a chainsaw. Chain will overheat and go blunt and chainsaw gets hot. If you just get it right, let the tool do the work, you get much faster results.
So im from an electrical background. I know how to use drills and stuff. Get an apprentice and tell them dont go in too hard? They listen but think leaning on the thing will do the job faster as they are trying to impress, but no, they smoke the holesaw and the drill needs a 5 minute break to cool down. So thats an example of not letting the tool do its job.
