I bought a piece of 1.5 inch stiff foam to try to fix a sag in a bed. It didn't work but having that thick piece of solid foam around has been a life saver....
My wife got me a fitbit. I resisted a little bit because I didn't want to have yet another device to monitor, charge, and maintain etc. I've been really surprised and impressed and how effective it has been in subtly encouraging me to make some small improvements in my habits. Not a bad deal for $100.
What is something really stupid you purchased that turned out far better than expected?
