Desultory: this is me. All over the place. "Flighty" is a good synonym. This is a word that I didn't really have in my vocabulary. I knew it was there, but to produce an exact meaning would have been difficult.
Much of my life has been desultory. I have flitted from one pursuit to another. Fortunately I've been able to stay married and make (sort of) a living throughout. While earning our daily bread I've pursued avocations such as ham radio, old-time fiddling, bicycling, a few attempts at novel-writing, and lately, poetry.
Aimless. Without a plan. Oh yeah.
