Result? Merry chaos. I propose an alternative that might actually work.

You don't have to succumb to the temptation of yelling back about how wrong people are. You can break the cycle. Here is an example of how to do exactly that.

This doesn't make them dumb nor wasteful, but that seems to be how many people frame the matter, so I have to use the word for SEO.

It feels awful! I hate it." The struggle is real, but I propose a way out: a way to have the benefits of the to-do list without the crushing anxiety and constant reminders that you're disappointing everyone, especially yourself.

Imagine seeing deadlines as an act of love! No, really! I believe we can make this happen together.

Focus on refactoring paths over applying the pattern "correctly" and universally to avoid having to choose between chaos and stagnation.

They also routinely argue, sometimes quite heatedly, about how to make code "more readable". I have noticed a conflict that they might be missing which could help moderate those arguments and make them more constructive.

I suspect that means that so-called "better" design will remain up to the individuals who decide that they simply enjoy their jobs more when they get to work in more-habitable code.

Michael Lopp's metaphor of "Blue Tape" offers another way to understand the power of Inbox Technique, which might help you (or someone who needs it!) persist in writing things down, even when it seems like they're doing it, but nothing's really happening.

The Rule of Three, a classic "rule" of refactoring, carries this risk. How do we reap the benefits while avoiding the drawbacks?

We have more confidence in it. I use someone else's article and example to illustrate what can happen. And no, you don't need to be a Wizard to do this.

Describing the concrete steps of getting started with GTD risks making it sound like pointless busywork. I propose another way to think about GTD that, I hope, makes it sound more compelling, both to get started and to stick with it.
