Welcome to my nightmare.
Just remember this, and life itself, is a practice. (I always liked that people say they
“practice medicine,” or they “practice law.”) You’ve tried various apps (as I did), and they seemed to help. “Ah, now I’ve got it.” Roughly: OmniFocus, Agenda, NotePlan, Passion Planner, Amazing Marvin, Paper and Pen, OmniFocus, Time Blocking, NotePlan, Paper and more Expensive Pen(s), Org Mode, Analog from Ugmonk, NotePlan, Org Mode, Paper and Pen. This has cost me hundreds of dollars, and a significant portion of my life (the irreplaceable thing).
But now you’re incorporating what you’ve learned back into your system, and posting here. That’s the practice.
As others have noted, the habit is important. Every day for the past 900 days, I’ve rowed on a rowing machine at least 30 minutes and at least 5000 meters. This is what I aspire to do with other things in my life. It’s hard to put into words, but I just don’t think about it, I just do it. I know that’s a common platitude, but I do think that I overthink things. “Should I…”, “What if…” I don’t do that with rowing. So perhaps a daily review would help me. Weekly is too infrequent, I think, and I lose the commitment. Should I do it Saturday? Nah, I’ll do it Sunday. Nah, I’ll do it Monday. Oh, it’s been two weeks. Well, it’s overwhelming now. What about Amazing Marvin
I don’t have any definitive answers for you – as you can see, I’m still on this journey myself – but wanted to offer some encouragement. Everyone is unique; others can only offer suggestions, not answers.
I have ADHD, and the most helpful book I’ve found to date, is ADHD Pro: Sustainable Productivity for People with ADHD, by Robert Merki. I’m not suggesting you have ADHD, just sharing a resource that has been helpful to me and others here on the forum.
Keep that feedback loop going, adapt and change, but don’t beat yourself up!
