In my case, if I travel somewhere for 3 days, when I get back, many of the routines I had at my original location will have evaporated no matter how long I had them, so I made a list, and have been trying to build a routine-recovering routine. It's slow going for other reasons but I've been very slowly working on it for 5 years now and it has helped at times when I've needed it (and remembered it exists).

Here's my additional tip to OP's tip: if you are someone who holds habits like a sieve holds water, you have to be even more intentional about forming habits, and form multiple interlocking habits that cue you. I'm at a very stressful time in life right now so it's hard for me to remember details but like, I wanted to develop a daily meditation habit. But what I had to do in order for it to actually stick, was develop a ritual out of interlocking habits: getting my tea, lighting some incense, doing the actual meditation, once finished immediately having a rewarding sip of tea, dusting off my cushion, writing a brief journal entry afterwards (this is the one that tipped it over the edge for me for some reason) with a piece of dark chocolate. I also put little succulents by my altar with a lamp on a timer that comes on in the morning, so just the lit-up presence of plants which I need to tend every few days draws me toward the altar if I've forgotten or postponed my sit.

You have to be like this with everything that doesn't come naturally. Yes, it's extremely intentional, which is exhausting. Yes it's a lot of hit or miss, trial and error, because of all the little sub-habits I just described above, there will be a number you try which end up not working for you. So you have to be persistent at messing around with your habit-sculpture long enough to find a permutation which works for you, and being persistent at things like this can be very difficult for people like us. In that case, I recommend sheer desperation, it helps with the persistence.
