Personally though I've got a bunch of fun stories to tell (what doesn't kill me makes for one helluva story) and I know a great many people, I haven't got the gumption to do it lol
This is a big one, if I can't fix it myself then I don't technically own it and a LOT of modern cars are in the same boat of making parts availability hell and the ability to fix them requiring special software tools.
I'm the same way with my cooking though I do have somethings I'm rocking at (comfort food in particular lol)
My favorite is when I bring a "boring" dish to a potluck and it gets cleared out in quick order.
I'll never forget my nephew when he was 5 saying how he hates sweet potatoes, and when he tried mine (after some coaxing) he became a fan. Nowadays (oh god it's been almost 7 years!) he's more specific and willing to try new foods even if they're normally ones he doesn't like, if they're prepared by someone else that is.
Different strokes for different folks, personally I enjoy a variety of differently seasoned foods. The base is usually quite similar for most of my cooking but variety is the spice of life.
I make my breakfast a week at a time (over night oats), my lunches are typically sandwiches made day of, and my dinner is usually pilaf or lasagna made in roughly 10 day portions.
Doing such large portions minimizes cook and prep time which is great.
