Next Actions v. Calendar
I like the idea that next actions are independent of calendar and should be organized separately.
This could be simple a sheet of paper in a 3-ring binder or, as I use, an Activities Checklist in a Time/Design planner.
This sounds really simple and obvious but it really does take some discipline to avoid the temptation to get calendar more involved in "helping" you with next actions.
While there a a lot of really good applications out there for GTD you have to be REALLY well versed in using them to get the true value of a trusted system.
Not sure why but I keep bouncing off various technology solutions (Omni Focus lately) back to my trusty Time/Design binder. Well, I do know one reason which is the BEST way to mark items complete ... a yellow Sharpie highlighter!
How did you capture that thought?
