I bought a sponge of sorts advertised as for getting pet hair out of bed sheets. I've no pets, but stress makes me lose tons of hair and I've long hair. It works like marvel for my own hair! It's so life changing! I love it!
I was also able to get a mini white paint with a mini roller for practically nothing to finish off the wall fixes I was doing.
I also got a tiny brush meant for keyboards and discovered my keyboard was super nasty with my hair on the inside. >____<
A bluetooth sleep mask. I am on my third one in about 4 years and it has saved me from lifelong sleep related stress. I am on round three of Discworld right now and love how I can use that to get my mind to stfu.
