Good for you! That is just one of the things people need to be doing in this day and age. The other is, for people like me who never went to college, is to go to school and get a degree and/or obtain new skills that will be marketable if your pink slip comes before you were expecting it. I swear I do not know what some people are waiting for.
The same applies to saving for retirement. One shouldn't wait until age 55 to start putting extra money away.
