Just an update - I took a look at where I am right now. Net worth rolled back 18 months to Mar 31, 2007 levels and the portfolio value rolled back to Sep 30, 2006 values (even though I've been pumping money into the portfolio these last two years).
But on the upside, yesterday's automated bi-monthly purchase executed for 37.8 shares of Vanguard's emerging markets index fund for $600 total. For that same amount of money, I would have only received ~18 shares about a year ago. In other words, I'm buying this fund at prices over half off what they were very recently.
In the short term this market correction is ugly on paper. In the long term this may just prove to be one of the best buying opportunities in my lifetime. Only time will tell. In the meantime, back to life - family, friends, career, intellectual pursuits, hobbies, etc - and let the portfolio do its thing! After all, the market isn't as bad as it seems.
