Current one is too outing to mention but past obsessions have been:
Jewellery making
Planning my wedding
Baby wearing (sorry) / slings
Tried going vegan for a while
Tried going sober
Dry slope skiing
Ice skating
Choir
Batch cooking/ slow cooking everything
They last about 2-3 months before I lose interest. No harm has been done but I do feel like a bit of a twat for being so consumed by things 😆 please tell me I'm not alone.
