My wife is decidedly NOT an MMM Badass -- however, this past year, she began socking away the max 401k contribution ($18k) and put her entire bonus (not a ton, but still) into our joint savings account. These were huge steps for her. She still spends way too much money on frivolous shit (viz., Lululemon clothing and shoes/boots), but in addition to the big changes above, she's also gotten very good about packing a lunch for work, making coffee at home (instead of buying at SBUX every day), and a couple years ago she agreed to cut the cord on things like our landline phone and security system, and other money-saving things at home. All in all, I'm quite pleased with her progress.
