To Collect Something or Everything

I like lots of pretty things, but I don’t officially collect anything. Not seriously at least. I often think it might behoove me to get serious about something, except that I am bad at being single-minded for long. I am great at short intense bursts of interest, but the idea of studying the esoterica of philately or the ephemera of numismatics for the rest of my life seems dreadfully boring. I just don’t consider any one thing important enough to warrant my attention for so long, and prefer to live a collage of assembled shells and books and rocks and plants and bones and vegetables and websites and foods and cetera.

I’m not sure that breadth of knowledge trumps depth however. Is there an objective answer to this one?
