I've been working through all the bits and pieces of my budget, my pay, and what should go where, and after some discussions with the husband, we're taking the plunge.
Just turned in the paperwork to put in the maximum contributions towards my 401K - $17,500 a year now. Considering we make well under 100K combined, I think that's a pretty nifty achievement.
Key to this is that we still wanted to live off of my paycheck alone, so that means for the foreseeable future, we'll be down to living on about 35% and saving around 65% total of our combined salaries (AGI). I think that is pretty badass (if we can pull it off). :D
