This comment really captures something that has bothered me for a long time about 'time management' People always say "I just make time!" as if somehow all time is equal. As if a sleepy afternoon hour when you can barely string together two sentences is the same as a peak energy morning hour! I try to put the most energy using tasks at the best times, but on some days, I have no good hours of energy. I have a lot to spend my few hours of energy on, and when I am working, I tend to spend it on work rather than recreational writing.
Of course, the heart of this issue of who surmounts impossible odds to write and who doesn't, is that it doesn't really matter all that much. Sometimes people in fact are just talking. Everyone who says "Oh, I'd like to write a novel someday, when I have time" does not in fact need to be told about how if they just wrote a hundred words a day, they'd have a novel way before retirement or told about how they need to make time to write.
Maybe they just like to think of themselves as creative, a little more interesting than their lives have turned out to be. And that's OK.
We all have little fantasies of ourselves being the sort of person who likes doing things that we really don't like to do. We want to imagine ourselves as the sort of people who travel to exotic locations and have adventures or do volunteer work, but some part of us understands that bugs, heat and exhaustion do not figure into our fantasies.
And so it is with fantasies of being a writer. People don't imagine rereading their words over and over and over to edit it, or being up at 5 am writing that new chapter. And that's fine.
