I Need A Bigger Whiteboard

Originally published at Amy M. Young. Please leave any comments there.

When it comes to writing, for the most part, I'm what is known as a "pantser". I can't write a strictly structured story. I've tried it, and I've failed horribly at it (It's in revisions, and stuck there for two years, unmoving because I can't work within the structure).
I've made moves of changing, seeing as the whole set of characters has two arcs that they have to run though, and I unfortunately have the attention span of a gorram gnat sometimes (y hello thar ADHD). Most of my "planning" is done via whiteboard (or if I'm in a crunch, index cards). The extent of my "planning" is writing out the major plot points that have to be hit - the beginning, climax and end. Everything between then, well, that's up to the little bastards to come up with.

Sadly, my whiteboard is smaller than I need and now I'm looking for a virtual app to do the same on my Mac. (On an unrelated tangent, Apple, get off your ass and give us a real fecking tablet, not an oversized iPod Touch. KTHANXBAI) Mindmapping doesn't work as well as it and I have structure issues (I tend to put a LOT of info in when it doesn't want me to).

I just don't get the over-zealous planners. I really don't. Mapping out everything for them to do takes away the spontaneity that can come out of a story (Like one of my characters stating that their manager would "shit a bird" if he saw this. Something I don't say and never would, but it came out perfectly for his way of speaking).
