I'm not a minimalist, though I fantasize about it. lol.
I have been working on simplifying my life for several years now and am making progress. Not "there" yet, but I AM closer!
I LOVE Elaine St. James book Simplify Your Life: 100 Ways to Slow Down and Enjoy the Things That Really Matter. One of my all time favorite books EVER.
I just ordered another book of her's titled Living the Simple LIfe: A Guide to Scaling Down and Enjoying More.
I've read several books on simplifying, decluttering and minimalism. There are lots of good blogs out there and even youtube videos.
Personally I have been overwhelmed with all of our stuff. It's just too much. We don't even live in a BIG house, but the moderate-sized house we do have is stuffed full of things.
I am thinking the point is too keep the things that you love and that work for you and get rid of the things that stress you out and don't work for you, so that if two sets of bowls makes you happy and works for your lifestyle, then keep your two sets of bowls. It may be less stressful if you do a lot of baking to HAVE extra bowls. For someone who does not bake much, the extra bowls might be a burden.
Here's website that I have found interesting.
