I meant to get back to you sooner, because your question actually made me think about my own routine a bit more.
I usually keep things simple when I am trying to stay consistent with a new habit. I pick one time of day and tie the task to something I already do without overthinking it. If I make it too complicated, I drift away from it within a few days. What helps most is leaving a small reminder where I will naturally see it, like near my keys or beside the kettle.
I also stopped expecting every day to feel perfectly organized. Some days are scattered and I just do the smallest possible version instead of skipping it entirely. That keeps the rhythm alive, which matters more than doing it flawlessly. If you want, I can send over the little checklist I use, because it is not fancy at all, but it makes the whole thing feel lighter and easier to repeat.

I was thinking about what you said, and I honestly agree that starting too big is usually the reason things fall apart.
When I know I have a packed week, I give myself an easier version at the beginning just to build momentum. That keeps me from turning one missed day into a full stop. I also try not to crowd my calendar with too many promises to myself, because I end up resenting things that were supposed to feel enjoyable.
What has been working lately is choosing one small goal for the week and checking in halfway through rather than waiting until the end. It feels less dramatic and more practical. If the week gets messy, I just adjust instead of pretending I need a perfect reset. I think you would actually like that approach because it leaves room for real life and still helps you keep moving in a direction that feels good.
