I've found that my routines are like seasons: the time and place for a routine just passes eventually.
This used to frustrated me. It's hard to build routines, and the initiation energy to resume the activity—and the effort to sustain the same routine—was higher than before.
Somewhere along the line, though, I realized that while past routines were hard to resume … others that were previously hard to start had become more natural … so I began paying more attention to where the "current was flowing," so to speak, and would use that to my advantage.
But my work schedule is variable enough that focusing on "X @ 7am every day" is not realistic. Yes, I should reorient work around my life, instead of my life around work. Easier said than done, and... even when I've gone through periods of that philosophy (have done it), it didn't have any noticeable impact on my health (mental or physical).
But... I just stopped because trying to hit that every... single... day - rain/shine/snow, while traveling on the road, etc... it just became ... boring. Well... some days "inconvenient" was a better term.
