economy of effort and design simplicity and optimization...I like things that are not going to excess difficulty to do something, and that make the most of their design features.
for example, some car commerical here (I forget which, one of the US makers) is advertising a 355 horsepower twin turbo engine in an suv/cross over that has at least a 6cyc if not an 8.
WTF!?! you need a complex twin turbo to pull a figure like 355 from a large 6 or small 8? was the engineering team baked? if it was a small inline 4, I can see it. but i think it was pointless, expensive, overly complex way to make their product. I hate that kind of shit. Its just more stuff to be maintained and break for no actual reason. like a physical incarnation of windows vista.
i obsess over having things make the maximum effect of the resources and work put into them.
Handwriting. When taking notes, writing a letter, etc., the pen has to be the same color the entire time (even if it's notes from class over 3 days), and the handwriting has to be the same. No all caps and then regular writing. No cursive and then regular writing. It has to be the same. The letters have to look the way I want them to look, or else I write the whole thing over. Like if I have a to do list with 20 things to do and I don't like the way the letter a looks on the 20th thing to do, I'll write the entire list over. There is no erasing, because the imprint from writing is still there.
