I turned 30 earlier this year, and I just hit 100K within the past week. It makes me feel great to look at Mint and see the net worth graph keep moving up! To think that from years 22-24, I was living paycheck to paycheck, to have this kind of cushion really is exciting. I've made a lot of changes (dropping cable, cheaper cell phone, curbing eating out so much) and realized that I made plenty of mistakes along the way, such as not contributing enough pretax income to 401k, purchasing a new car for an eight mile commute, and maintaining unnecessary excessive expenses. I'm still looking to optimize a lot of things, but the momentum is building, and being a 'numbers-guy', seeing the dollars creep up proves I'm doing something right!
I'm shooting for less than 4 years for the next 100K! Thanks everyone for the great posts, they are really helpful!
