Biking - It's uncomfortable, I don't feel safe, and I'd rather walk. Plus I don't feel like cramming a bike into my tiny apartment (or paying $80/yr to keep it in the building's storage area).
Short commute - I love where I live, and my 1.5-2 hr. bus/train commute is fine, and my job pays for (most of) it. I can read, sleep, do homework... whatever I'd be doing at home, really. Plus I only do this 3 days per week.
Line/hang dry - No room. And I hate laundry/ the last thing I want to do is prolong the experience.
Never eat out - I like being able to give people money and they give me prepared food. This goes all the way from McDonalds (occasionally) to fancier places (we fully anticipate that our anniversary dinner will be $200-300, but we enjoy it immensely and budget for it accordingly). That said, I do cook most meals at home and almost always bring my breakfast/lunch from home.
Retire early - At FI, I plan to quit my well-paying job and go do work I'm interested in. Work in a tea store, work in a game store, dog walker/sitter/trainer, baker, etc.
