Finishing tasks have a deadline, or are time/day sensitive is simple more or less. But the tasks you can do today, or tomorrow, or the next week? A nightmare. Of course, you can define for those tasks also a deadline. For me this never worked. I found a great way to deal with these tasks.
Not a whole year ago we moved in, now we will move out. Crazy. I'm cleverer now, I hope this time this will be not so painful. Last year I downloaded some moving planners - they fitted roughly on our situation (moving in America and in Europe an other story) - now I know exactly what we need in a moving planner, so I already started to design it.
Organizing - anything - is a weakness of ADD people (like me) - this is the reason I highly interested in, and trying to make more fun, and overcomplicate most of the time :) Because the filtering function of the brain functioning weakly - we cannot see what is important, what not, start 1000 things and lost in details. We need lot more effort and organization as other. The problem with a paper planner is, that it has no notification function. You can write everything very organized and planned into your planner, but it will not say you: "hey, it's time to go!". Automation is very important for ADD people. And we are in lucky position with our smartphones, computers and smart watches.
