Like most designers, I spent years playing around with my personal identity, trying everything from custom initial icons to handwritten logos. About two years ago I settled on a simple (some might say generic, but that's fine) wordmark. I think it suits me.
It's about as simple as it gets; my surname set in Gotham Bold, with a few minor tweaks. I recently refreshed the wordmark by increasing the tracking and pairing it with a new icon. See the attachment for more.
