I think in terms of long term plans, having a solid routine really helps on weathering the ups and downs that occasionally happen due to circumstances out of our control. The hard part is getting back on track after such circumstances happen. Sometimes, it seems to me that there are only two options, get back on track just as before or get back on track with adjustments that match with the new changes. I mostly prefer the latter because there's an element of change, which means less boring routines over time.
