Happy early bday and congrats on your financial planning. I too would like to retire by age 55(34yo now) and it's quite rewarding to see others do so on a normal type of income. (I'm not aware of your income but a generalization made from the forum info)
Well, craiglepaige, I won't let that misimpression hang out there -- I make a lot of money, or at least to me, it is. I'm the higher earning half of a DINK household that is somewhere near the top 5% according to IRS info. It wasn't always this way though. I started out making (for a Top 15 law school grad) a modest $38K/year. But I began saving into my 401k right away, and with each successive promotion/pay raise, I increased my contribution until I maxed it out a decade ago. And my wife, after years of mostly stagnant wages, has gotten ahead in the last couple years. I won't call myself frugal, but I'm far more conscientious of spending then a lot of people I know who make my income, and I'm not into the consumerist culture. I don't have things that my friends consider indispensible, like premium cable channels, DVR, PlayStation, season tickets for my favorite sports teams, the very latest smartphone, fancy cars, and the whole shitload of crap I see people regards as needs instead of wants. I have taken the MMM thing to heart though, and significantly cut expenses on many things (and am much happier for it!). But we spent a significant sum for housing (though only 1100 sq. ft), my wife and I travel a lot, I maintain several fitness memberships (regular gym, climbing gym, jiu jitssu) and we eat organic/grass-fed, etc (i.e., we spend way more money on food that we have to, or probably should). So thanks for the kind words, but I don't think many on this forum would consider my household income "normal," and I definitely have lots of room for improvement! But sure, I'll take credit for making sound decisions on a lot of the fundamental things, the most obvious being to not live beyond one's means (though even there, I stumbled in the early days).
