I'm frustrated with my tendency towards indecision, and I react by overcompensating. But maybe I could let slow choosing protect me instead. Especially financially!
I get on a tear for about a month at a time about one thing (interior design currently) and I want to upend my material possessions. I'm obsessively thinking about money and furniture right now and the occasional reward of the great FB marketplace find temporarily justifies the time sink of it all. I feel the pressure of grabbing something before it's gone and to fill the room I'm working on with all the little details that will perfect it and justify the time spent. But at the end of a search, online shopping and even just window shopping makes me feel depressed and like I'm wasting hours of my life on insubstantial nothings. Making one purchase greases the wheels to make another and the desire to consume exponentially increases while the satisfaction dwindles.
The rec is to let the dust settle before reacting to change. Even if you have barriers that will physically prevent you from making your next decision, like a budget forcing you to wait on a following purchase, don't invest time researching that next decision until you've figured out how you feel about your last one. Move all the furniture in a room around and leave it for a few days even if it's sort of worse, put all the knick-knacks in a box and then take them out again, write down everything you want to change on a piece of paper and leave it on your desk for a week. Draw a picture of your vision and tape it above your bed. I drew literally 6 different versions of the room I'm sitting in and it's still in a different state than I could have predicted I would have chosen.
My favorite thing in here now is a collage I made years ago which I dug out of a moving box in my closet and stuck in a dirty frame my friend thrifted. It's a crappy DIY and I had to use a claw hammer to bend and unbend the nails holding the backing to do it. I hated the result, but left it on my desk anyways and now it makes me happy every day.
