Seek out small investments that return outsized quality of life improvements.

For example, I've been growing my hair out this year. Never before have I had to deal with knots, and I quickly learned that they aren't fun.

I switched my generic plastic comb for this wide-toothed wooden comb, and I've been amazed at how much better it feels. Never going back. Probably never buying another comb again assuming I don't somehow break this one.

Another one that I highly recommend for everybody is tossing a water filter on your shower head, they're like $50 and will change your life.
