The way you are using it "square minded" seems to me to mean "isn't interested in obvious scams." The items in your list sound like scams to me. You'd do better off exercising and being more active (to heal your body) or just trying to build the thing you want to build rather than asking someone to tell you how to do it.

So, largely I think I feel the way you do about those things, but I don't think that's bad in any way. They seem like a waste of time.
