Sagittarian writer Samuel Clemens was best known under his pen name, Mark Twain. But he tried many others, including Thomas Jefferson Snodgrass, W. Epaminondas Adrastus Blab, Trismegistus, and Sergeant Fathom. Since you're in a phase when experiments with your persona would be productive, I suggest you dream up a few aliases of your own. I hope that at least one of them will be as wacky as "Blab" or "Snodgrass." Having a sense of humor about yourself will be helpful. It will ensure that your explorations at the frontiers of your identity will be fertile, fun, and never fear-based.
