The public, and even acquaintances and friends, generally identify me as an entomologist who writes about insects and spiders, but there are a few other subjects that interest me and that I hope to be able to pursue. Generating a living off any of them is probably unlikely, but you have to do what you are passionate about, too.
While insects are what I know most about, most aspects of the natural world captivate me. I could stand to learn a lot more about plants, for example. It will be harder for anyone to turn me into a maniac for geology or mycology, but I am happy to pick up knowledge here and there. Now that I am taking images of living things instead of collecting specimens, I am more apt to point my camera at birds, mammals, reptile, amphibians, and wildflowers and mushrooms. Thanks to social media, I can share what I find and learn from experts in those fields.
