The list of ever-changing hobbies have cost me tons of money is by biggest complaint. Any new hobby I find interesting leads me down a financial rabbit hole of buying “everything I might need”! Any hobby that involves “buying gear” excites me, and I soon find myself spending tons of money (or charging) to do it.
I have spent thousands of dollars on hunting gear and found myself bored with it all only after three seasons. I’ve spent a bunch on other outdoors activity as well only to fill my garage with stuff I never use (but might some day!)
My passionate interests have changed at least 10 times in the past 20 years, with a house full of relics from hobbies gone by!
I’m “into photography” now with several thousands of dollars spent so far in only a year and a half!
