I could write a really long post about this, but I'll strive to keep it concise. It's something I've really struggled with the past while. Over the past couple of years I have implemented GTD more and more in my life because it seems to be the best system I can find to capture, process, organize, and review everything. I have struggled with the "do" stage however. At some point along the journey of GTD, I assume most wrestle with understanding the two-headed beast of procrastination and motivation while trying to master the do stage. I have observed the past year that my motivation is inversely proportional to the number of projects/actions on my lists. The larger they grow, the less is my desire to work the lists. The shorter they are, the greater is my desire to crank through it. My struggle is this: HOW to limit my lists. I have tried the following: (A) Allow an unlimited number of projects (i.e. as many as are on my mind to any degree) (B) Impose a soft limit to my projects (i.e. only that which is truly essential for me to work on this week before my next Sunday weekly review) (C) Impose a hard limit to projects (i.e. absolutely no more than X number of projects at any time; must relegate or promote between projects and someday/maybe lists as necessary to maintain hard limits). (A) is too overwhelming. I'll probably never go back to that. I gravitate toward B or C. The struggles I have with soft limits: it invariably ends up growing relatively "large", around 20 projects. This means 20 actions, of which only 10 may get done in a given week. It starts feeling like (A) quite soon because I don't feel like I'm making much progress on any of them. The result is that my motivation drops somewhat. The struggles I have with hard limits to projects list: I'm not quite sure whether to impose hard or soft limits to my actions list as well. If the actions list has a soft limit, then I start allowing anything on there, and it starts becoming overwhelming again. If I impose a hard limit, then I find I need to review my someday/maybe list daily (or even hourly) for the small single actions. It's hard to explain all of this but it's a real struggle for me. It may sound like I'm overthinking it, but it is truly a sticking point for me. What do you all do to limit your projects and actions lists? You might say I'm just trying to understand how to somehow integrate the Kanban principle of "limit work in progress" (LWIP) with the GTD projects and actions lists. LWIP just feels right to me. But how to do you place limits on projects and actions lists, when the GTD principle (and often my psyche) says "your work-in-progress should grow as big as you need to get it off your mind". Dang it. That was not concise. Oh well. It's helped to get this down in words.
