My second character is on his 5th year, currently having a winter vacation from a building project that lasted more than half a year.
Usually there's no fixed routine for him but hey, do the right thing at the right time save you tons of efforts. Besides I become lazier since the latest update nerfed smoking food while keeps drying food unchanged, so here's what a typical year of his life looks like:
Late autumn - winter: Hunting, mostly big games. Usually I wait until the time when snowing is less frequent so animal trails is much easier to see in screen, then pack furs to my bull for kota and bring my hounds with me to hunting grounds I founded earlier, a nice large area of mires in kaumo land. The aim is simple: bring home as much as the dried meat you need in the next year, so I won't have to smoke meats in summer as it is far too time consuming in current update (but I still like this change, ha)
Late winter: Idle. Daydream next to my still warm with ember fireplace. Make lots of stew. Feed dogs. Fish occasionally. Practice skills. Experiment on things. I mean, animals are most likely hiding in this freezing time of the year, and I did hunt in this season once and end-up nearly freezing to death, not going to do it again.
Spring- Very early summer: Mostly farming. I like the views of different crops grow across my field, though I don't actually rely on crops to live. I also do some of the special rituals since my time is quite flexible in this season.
Early summer- Autumn: My "project" season. Every time in this season I come up with something that require a lot of time and efforts. i.e. This year I built a very large barn, last year I explored the entire southern coast.
When I feel bored I usually patrol around my settlement and wander to nearby villages and see if I can get quests or not.
