FIRE is a lifestyle and in my view the main goal of it is effectivity. Retiring for the sake of retiring does not make one automatically happy. Instead you should understand what makes you happier and optimize for it. As a result, FIRE does not mean "don't spend money", instead it is "don't spend money on stuff you don't care about". Thus, I disagree with commenters framing FIRE as "living in poverty to live in poverty without a job". One can be FIRE (or on track to) and still live a great life spending enough money to be happy.

That's why I think your question is a bit backward. Instead of wanting to reach FIRE in 10 years, try to understand why you want it. FIRE is just a tool giving you ~40 additional hours per week. Why do you want this time? If one is unhappy with their life before FIRE, they will just have 40 more hours to be unhappy.
