I've Run My Life on the Same System Since 2009
In 2009 I built a little web app to run David Allen's Getting Things Done® method, because nothing on the market at the time would do it without a fight. I called it SmartyTask. I was 49.
I'm 66 now. In between, the productivity world invented and abandoned: nested everything, Inbox Zero as a religion, kanban for your groceries, gamified streaks, second brains, zettelkasten, four separate "Notion killers," and AI that promises to do your todo list for you (it won't; doing the list was never the hard part).
Through all of it, SmartyTask users kept logging in and quietly checking things off. 236,000 completed actions and counting. Some of the people using it this morning signed up when gas was $2.40. Seventeen years of watching real people run the same simple system, while the industry sprinted through fad after fad, taught me exactly one big lesson, and I want to write it down.
Tools don't fail people. Maintenance kills systems.
Every productivity system dies the same death. Not dramatically. Quietly. It dies the week you're too busy to maintain it. The elaborate tag taxonomy needs grooming. The priority matrix needs re-scoring. The board needs re-balancing. And the cruel joke is that the week you're too busy to maintain the system is precisely the week you needed it most. Your system fails exactly when it matters. That's not a tool problem; that's a design problem. Anything that requires maintenance energy will eventually be abandoned, because maintenance energy is the first thing real life confiscates.
GTD® survived seventeen years of my actual life (businesses bought and sold, kids grown, a couple of proper crises) because it asks for almost nothing. Capture takes seconds. Processing is a daily five minutes. The weekly review is fifteen. There is no taxonomy to groom. When life went sideways and I dropped the ball for two weeks, getting current again took one honest review, not a weekend rebuild.
That durability is the entire reason SmartyTask looks the way it does. People sometimes ask why we haven't added kanban views or priority scores or AI suggestions, as if the answer is that we haven't gotten around to it. The answer is that we got around to it years ago and said no. Every feature you add is a maintenance tax you levy on a stranger's worst week. The feature list is what's missing, on purpose.
Here's what seventeen years says actually matters, in order:
Capture that's everywhere. If capture has friction, the system starves. It has to work from the truck, the kitchen, somebody else's office. (It's why your SmartyTask inbox has its own email address. Forward anything, it's captured.)
Lists you trust. One flat projects list. Next actions sorted by where you are and what's in your hand. A calendar kept sacred for real obligations. Trust is the product; everything else is packaging.
A weekly reset. Fifteen minutes that makes every list true again. We finally built the guided version right into the app this spring. It walks you through, shows you which projects stalled, and lets you finish. The finish line is the feature.
Nothing else. Genuinely. That's the system. Three habits and a place to put things.
The 2026 version of SmartyTask is faster and prettier than what I built in 2009. It's on your phone now, it pings you a morning digest, and it'll put a deadline on your calendar in one click. But a user from 2009 could sit down at it today and be home in ten seconds, because the bones never changed. The bones are David Allen's, and they were right the first time.
Seventeen years from now I expect the productivity industry will have burned through another forty revolutions. I expect to be 83, still doing my Friday review at 4 o'clock, still checking boxes on the same flat list. Some things work because they're new. The good ones work because they're true.
