I'm not planning a kitchen redo, but I've been there when the oven died, and I REALLY wanted a new one instead of repairing the old one...
When I first started on this journey, I looked at my budget, imagined everything I could cut out, and was so excited about how early I could retire. If only I cut out everything that didn't fit properly into bills and tiny amounts for fun. What ended up happening would be little things would piss me off. My preschooler had to bring food for a potluck, but I'm not allowed to bake because *ALLERGIES*, so I have to go to the store to buy something special and now I'm angry. Didn't they realize that $7 was supposed to go to my retirement?!? AARGH, that's so rude!
The only thing I did was make my budget more realistic, recognize that we're always going to have those expenses come up. And we ask ourselves those questions. Do we want to get a newer car, or would we rather retire 6 months earlier? Whatever we decide, it's our decision, so we don't have to get angry about it.
I am also disappointed that the stock market has pushed our FIRE date out. I could see myself getting angry, but I just think about the even higher returns we'll get eventually.
