Last year I bought a retractable clothesline cord for 10 bucks to air dry my laundry instead of paying 2 dollars each time I used the dryer! How much did I save? Probably less than $50. Was it worth it? Nah! I had to spend a lot more time dealing with my laundry.
Poor people spend time to save money but rich people spend money to save time.

To answer your question, probably 7.

Probably an 8. I like to be efficient and being frugal is part of that, at least so far as when it is worth my time to be frugal.

Hm, I'm more minimalistic than frugal. I do not need very much but what I want and many things I need should be of good quality and therefore last longer. Some with people. I only need and want a few but the relationship should be good and long lasting and hopefully be of some depth.

Depends on the day properly about a 10 most times.

Used to be 1… now it’s 7-8

Um, about 3-4 😆

2 not very, it's not like I'm leaving anything for anybody

Used to be a 9, now it's 7.
