Oh, we think about doing it, a lot. We're even sad we haven't done it. We're aware it's easy and will only take a minute too. We just... can't, yet. The reason is unknown to us.
The only way I get things done is by doing something to procrastinate at something else I should be doing.
Couple this with inner restlessness and the guilt I feel for not getting the things done that I need to and voila! We have productivity!
Granted, it's all in the wrong order and I'm exhausted due to my inability to just sit down and relax for a minute. But, look at all the stuff I've gotten 3/4 of the way done! Pats self on back
Often it's the ones that only take a second or a minute and minimal effort that get put off the longest and create most anxiety. I was discussing this with a friend last night: I've had numerous non-ADHD people explain to me how I just need to create a task list, not realizing that 1: I know all the shit I have to do...I'm just...waiting..., and 2. When I do try to set up lists and organizational systems, I get sucked into a false productivity hole and spend an inordinate amount of time on the process/list/automation crap, and then when it's perfectly set up, I maybe use it for a week but inevitably revert back to the chaos
