Inspired by the "worst financial mistake" thread! What's the best financial decison(s) you've made in life? For me, it's four things. 1) Starting my 401k at age 23 2) Buying a condo when I moved out of my parents. Best investment I've ever made! 3) Buying my car instead of leasing, and when paid off I kept the car instead of going out to buy a new one. 3 years of no car payments has been wonderful! 4) Keeping my credit history spotless. Everything is paid ontime no matter what. What are the smart decisions you've made?
