When you write for a living, you will probably cram your schedule with as much writing as you can, and many projects at once – some short-term, others, long-term assignments. A lot of time can be spent in projects that do not generate enough income. Learning to decide which projects to put aside and which ones to pick up is not as easy as it seems.
While a project may give you instant rewards, another will reward you much more in the long run. Also, you may have to put aside your favorite project to handle a more profitable one. Or you might have to cut a project to a few days a month, if that project is not generating what you want – and sometimes, cut it altogether.
This is why writing for a living is like a juggling or balancing act – you have to be balancing projects and deciding which ones to give a priority, which ones fit your needs at the moment, and which one to drop or revisit later. Timing is also important, as a project that may have seem profitable initially, may not be, if you are spending more time in it than you originally planned.
