Good idea. I think getting through the house and making a "sell" pile is a good idea. I also just found out this week that the new 17.5K 401K does not mean my contributions + company match. I always assumed co. match + contributions should not be over 17.5K. However, it appears the Co Match does not count "against" the 17.5K limit (assuming your are not in the catch up scenario). That being said, I think it will be very difficult to max my traditional 401K + my own personal Roth IRA.
All the more reason to make a "sell" pile
For me, it was cutting out services that I was paying for but not using. I cancelled magazine subscriptions, gym memberships, cable tv, etc. Another "frugal" choice is to go ahead and sell off stuff that I don't use. I thought I was going to get into photography and started collecting gear (second hand, mostly) and now that my interests have changed, I've gone ahead and sold off that gear. I' m glad I was able to have fun, learn about lighting and composition, and now I'm able to move onto my next hobby. I'm also selling my used books, sports watches, electronics gear and other crap that I thought I'd get into, but have lost interest in.
My other tip is scheduling regular transfers into my EF, aggressively paying down debt and not letting money just idle in my checking account. I max out my 401k and Roth each year. It's always a stretch, but as long as the money doesn't stay in my account too long, I'm not tempted to spend it.
