It doesn't have to be anything cosmetic but just something that you take time out of your weekly schedule to do for yourself. I wouldn't say I have anything consistent that I do but I do like to take some time and go for a quiet walk every now and then. I also like to do an at home spa night where I'll do my nails while watching a movie or something along those lines. I try to find anything that can take my mind off of work or whatever is going on for a bit lol
