First, This question is a lot deeper than probably can be answered in a HN comment... but in theory the only thing that changed for you by working from home is the amount of time that you "see" other humans... I would offer that the first place to make an adjustment should be there. Human beings are social animals and we need time around other humans. If you aren't currently getting enough of that you should add it into your life (like working out, or sleeping 8 hours a day).

Second, a while ago someone reframed the "motivation" concept to me and it's been really beneficial. It's easy to think of "motivation" as an extrinsic concept, but most of what we call "motivation" is actually better termed "discipline". It's a lot easier to fix "discipline" issues than "motivation" issues.

Lastly, if the issue is deeper look into the japanese philosophy of ikigai.

(I also find music can be pretty useful)
