my favourite is cooking, though I often forget how much I enjoy it because I'm too tired/busy/stressed to do it! same goes for watering plants. tending to plants can get pretty therapeutic but not when I'm feeling overwhelmed with daily life and don't have the focus or motivation to do so.

my least favourite chore is definitely washing the bathtub. it's hard on my back/joints, and I'm afraid of mold (although my fear of mold means the bathtub is clear of any). shovelling snow is hard on my back too, but if it didn't cause that kind of pain I might actually enjoy it.
