I used to spray all my clothing with Static Guard every single day because I can't stand static cling. I forget what prompted it, but a couple of years ago, I decided to skip it on cotton clothing and fabrics less prone to static, and then I also realized static wasn't really an issue most seasons of the year. I'm now at a point where I hardly even use it at all.
Fabric softener dryer sheets - I know these are controversial, but I have continued to use them, only cutting them in half. The past few months I have experimented with skipping them completely and hang-drying things like fleece that are the most static prone (apparently the dryer promotes static?). I'm finding I really don't need to use these very much at all.
Perfume - about a year ago, I was running low on my favorite perfume, and realized it was getting harder to find and more expensive. I went from "I need to buy perfume" to "hell, no one EVER needs perfume," which both simplified my life and helped my budget.
Similarly, they keep discontinuing the colors of nail polish I like, and I've decided clear polish is the way to go, simple, seems to dry faster, and I actually get compliments on my nails, so I think the important thing is to have clean, well-groomed nails.
Has anyone else found that something they thought was needed isn't really needed at all?
