When I was first born til probably 5 years old, as I wasn't making anything at that young age.
My parents taught me to save at minimum 10% of everything I earned, and by the time I got into college I had a good chunk of $ saved up. I then got full scholarships for everything, and I've never been broke. I'm not rich, but at least I have enough to live on for quite a while if I ever lost my job.
My parents are struggling now, and are just breaking even which sucks since their retirement fund was destroyed when the market stared to drop. But at least everyone is out on their own now, so they just have to provide for themselves.
