But I don't sleep well if I don't write every day. Some internal processing mechanism of mine has come to depend upon getting some of the words out of my head so that's it's quiet enough for me to get to sleep.
All prickly keep-out's, should's and you-oughta-be's. Being inhospitable to one's self though is very short-sighted isn't it? You're the one you spend the most time with, and your ongoing, life-long conversation with yourself is pretty important. So really, c'mon, it isn't selfish to take the time to write, if that's what's required to keep that conversation going. And to get to sleep.
