Yeah, without knowing what the goal here is, it's impossible to say. Fastest ER? Live in the tiniest shittiest apartment you can find in the cheapest poorest part of TX with no state income tax. Don't leave your apartment except to shop for beans, rice, and MREs. Alternately just order MREs from Amazon. Work 18 hours a day. Pile up $ as you turn pasty white and develop a health condition...
Sounds horrible to me. If you don't know where you want to live ("Tahoe and work from the lift and get 100+ days in!", "NYC and hit every Broadway show!", "Ceuse and drink fine wine every night, finally send an 8b!") I sort of wonder what sort of life you want to have after you're FIRE. You must have outside interests, friends, family, weather/climate preferences, etc, right? Right?
Forget money for a second and decide what you want to do with your life. This is a preview of what you will have to figure out once you are FIREd.
