Wow, just wow! High salary, no debt, paid for house, no taxes, high savings rate. Best. Start. Ever. :)
I have a question for your for clarification: you mention your employer takes 15% for your retirement account, which you get after about 25 years. What will happen to that money if you retire early? Also, what kind of timeline are you looking at to retire? 5 years? 10 years? Stay the full 20?
