I reached my coastFire number last year. I was interviewed by a smaller firm in the same industry I currently work. They said I impressed them and they thought I'd be a great fit. They offered me a role at a higher level with a 20% base increase. I turned them down.
I feel like this was my first decision with the coast mentality. I could've done it but why leave an organization I'm comfortable with and coworkers I'm used to to go to a higher demanding role with almost no support to speak of (much smaller company).
Would more money be nice? Sure, but I don't think it would be worth the stress and lack of flexibility and time off to spend with wife and young son. Thinking of it in terms of coastFire has really helped me not regret my decision.
