As I work toward FI, I find that something that helps me stick to my goals is to imagine myself retiring at the end of the year, and then figuring out what I would have to do to make that happen. So I think to myself:
"If I could learn to live on ____, then I could retire at the end of the year."
This is nice because it requires a (somewhat unrealistic) goal for both spending and for your savings. Right now I am at -- "If I could learn to live on $20,000, I could retire at the end of the year."
--- I haven't learned to live on $20,000, but I am working my way there!
