Still thinking about multi-tasking. Then I stumbled upon this fantastic blog post by novelist Christine Fletcher about breaking up with a work in process (leaving it for a new novel).
Completely cracked me up. Also got me thinking about passion. Commenters on my previous multi-tasking post all admitted to failure at working on multiple things. You said that once you shifted your passion for a project, it was hard to get it back (and the reverse, if you were passionate about a project, you had to see it to the end).
That has been what's scaring me, too. I am passionate about my current work in progress. I believe in it. My tutors and classmates believe in it. I can't afford to abandon it for a shiny new thing. So my goal at the moment is to continue onwards, to finish my wip. And when I get stuck or bored--I'll sneak around a bit and do some casual drafting with my new idea. Just a little cheating on the side--will my current wip even notice?
But I assume, like all of you, I'll hit a point where that's just not possible anymore and I'll have to make a choice. If I still love my wip, and I think I do, it will force me to choose it. I'll let you know how it goes in the meantime.
