Great perspective Ellen. I consider these writing challenges similar to 30 days fitness challenges! The intent matters most - why is someone doing a challenge.. if the purpose is to get started and meet new people.. then it's great.. do it and make sure you continue even after those 30 days... but if the intention is that the 30 day challenge will give you some magic portion that will make you an amazing writer, then you are setting yourself up for disappointment... well written piece, thank you :)
