What is something really stupid you purchased that turned out far better than expected?
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.
Need something flat to put a laptop on? Throw it on the foam. Going to be doing something that requires you to be on your knees for a while? Get the foam!
It went from stupid purchase to something I'd gladly replace if it broke.
When Teavana still existed, I bought a teapot and some "teas" (Teavana was mostly herbal tisanes...but still.)
I don't drink coffee, so I imagined the teapot wouldn't ever be used...but somehow it ended up being a big hobby for me. Bonus: fancy teas from online stores are cheap to ship, because they're basically dry and lightweight. Like, if you want to become a food snob about anything? Tea really is the way to go.
The one learning curve I had (as an American) was learning that you DON'T steep the tea longer for stronger tea. You use more tea leaves/more tea bags. Steeping too long turns the tea bitter. (I thought I disliked tea when younger b/c I'd only ever had cheap tea bags left to steep for far too long.) Also, when brewing a green tea, they're really reactive to boiling water, so you REALLY don't want to use boiling water or it'll be a bitter mess. You want to either boil then let it cool, or get a fancy electric kettle where you can set the temperature so it's appropriate for green tea, oolong tea, or black tea.
I got addicted to PG Tips extra strong blend when I was in the UK and now I import it. I feel like such a snob, but I don't care. They wouldn't think I was a snob for drinking it in the UK!
There's a small tea retailer in the UK, What-Cha.com, and the owner does a "mystery tea" option which he uses to get rid of slower-moving teas, or teas he might have had to buy to get a better choice on a tea he wanted to get from a wholesaler. Or sometimes teas he just wants people to try.
"Mystery tea" sounds dodgy, but it did a great deal to expand my horizons, because even these mystery teas were really, really good (far better than ANY grocery store tea in the USA) and opened me to teas I might not have otherwise tried.
I'm TOTALLY a snob importing teas from the UK...but what can you do? America is a coffee-culture country, not a tea-drinking place, and the local stores just have tisanes or crappy bottom-tier tea (basically, tea dust from processing higher grades of tea is packaged into teabags and sold in grocery stores--and people don't know how crap a tier of tea that is!)
I've had great luck with Upton teas for the past decade or more in the US. Great selection, teas at multiple price points from broken leaf to first flush single estate.
Oh boy. Similar story for my wife and me. Now we've got 3 gaiwans, 4 yixing clay pots, and two cast iron pots. And now we do a little tea ceremony everyday. It's a great way to just sit together and chat without other distractions.
I never quite got into the tea ceremony part, I admit. (Maybe because I live alone and don't have anyone to share it with.) My first teapot was glass, and I like viewing the color of the brewing tea. Plus, the gaiwans/yixing are so small...I'd rather brew a big pot and have it last than have to go back to re-steep teas.
I know I'm probably missing out on the experience of the tea changing flavors subtly as it's steeped and re-steeped...I just can't give up my big glass pot, haha.
