Wow, I really had no idea what I was getting myself into. A a 50/50 joint venture structure really makes it to hard to get anything done. I've not posted an update here until now because I've been fighting to keep the JV from falling apart. Every month it seems a new roadblock appears. It's been a roller coaster.
I've taken a total of maybe 3 days off in the past 6 or 7 months and I have no work life balance. My big 40th birthday came and went without much fanfare (no time).
The positive aspects are that I'm learning a lot and each obstacle I overcome gives me more confidence. I love the local team and living and working in Mexico has been the least of my problems.
My monthly expenses are only 2/3 what I spent before and for the first time I reached the crossover point for FI (assuming current expense and 4% WR). Firecalc today confirms a 98% success rate for FI in 2 years with my previous spending level.
I don't regret my decision one bit, at least today. Ask me tomorrow and I may have a different opinion.
