In his own words: FIRE … “Early retirement is a marathon, not a sprint. Being overly obsessive about early retirement can be a detriment to your health, relationships, and social life. You have to pace yourself when you’re chasing early retirement. It is impossible to sprint the whole way. You’ll burn yourself out if you try.”
So many people that are new to FIRE make the mistake to going full throttle when instead you should be pacing yourself. Joe’s fantastic post has some great tips for how to go all out in the beginning, then scale back once you hit certain points.
