Mind-Catching
I like the Challenges because they inspire me to write. Sadly my own muse has the attention span of goldfish, hence nothing I ever try to start ends well (or at all). Yet here I can spit out a short poem or ramble on for a paragraph or two and feel accomplished. Strange.
I'm not sure which Challenges grab my attention; I tend to scroll through until one incites an idea. I agree with other Prosers here that people tend to read Challenge entries more, since it seems like a way to gather up similar-themed pieces in an easy area for perusal. Yet I've never been interested in who wins -- just seeing if anyone enjoyed my writing or if I can find any pieces I enjoy myself. I think that's the real success there.
I have realized that despite my best efforts to maintain my grumpy curmudgeon status I tend to write about my partner a lot. I suppose that's romantic after ten years together, but it does seem silly sometimes when I look back at the ridiculous amount of poetry it's inspired. I've decided to finally print some and share them for V-day (I have not shared a single piece of my writing with my lover - it's never occurred to me). They will be titled, "I Never Believed in Soulmates: A Collection of Reluctantly Romantic Poetry" and dedicated to my love, "whose fault it all is". Most likely, they will be glanced at and forgotten; my love is more into numbers than letters.
The only other trends I can see are my random rants about life as a lowly wage slave, which tend to be my most passionate pieces besides those above. Perhaps the two things that drive me most are love and hate -- mayhaps the Challenges that draw those emotions out then draw me the most.
