I think there’s something to that statement. Hell, my old job was essentially just a form of data entry, but I managed to find things interesting with it and actually rather enjoyed it. Pay was shit tho so I went back to school to get to where I was now. But I for the most part agree with you. You can find interest in many things if you try hard enough. Not the case with some, for sure, but it’s definitely more than some people realize.
And being interested about a topic makes for a good jumping off point when getting to know someone.
