Since watching three crows attack my lawn as a smorgasboard for bugs, some years ago, I have worked on a poem to work out the malaise I felt over their arrival and the outcome of that malaise. Writing is something you do every day if you want to be a writer, but you don’t always work on the same item day after day. sometimes a piece needs to sit–like soup or sauce–to coalesce in your heart and mind–before undergoing another revision.
Write every day–but don’t kill yourself over a piece that is not working out. Put it aside for a few days–not our of mind, just out of sight. Work over some ideas in your head and then try them out on paper. Leave enough time in your work schedule for each piece, especially the deadlined pieces, for this creative “rest” period. Some pieces do not need it, but many do –and it is usually of great benefit.
If it is a piece that is not under contract, once you have fulfilled its needs creatively, that is the time to find a market for it–often a more difficult task than the writing!
