Engineering versus Philosophy

I find myself being interested in too many things. I don't have enough time to devote to so many interests. At times I end up asking myself: "what the point of this particular interest is?" So often I find that I do actually know. I know that there isn't much point and I get frustrated, even angry at myself for all the time I seem to have wasted. It can be likened to a fishing lure. I see something shiny, or a single appealing attribute, and then next thing you know I'm hooked and begin the long struggle to avoid being "hauled in".
