Gee, what took them so freaking long to figure out that carrying a lot of debt is bad for you?
I began my savings and investment program when I joined the U.S. Army in 1959. One half of every pay raise went into savings, and as soon as I had enough, into Mutual Funds. I continued that program for the 10 years I spent in the Army, and came out with about $40,000 (US) in investments.
I suspended this while in College/University, but resumed as soon as I was employed again. I did this right up to retirement.
The ONLY things I bought on "time" were homes. I paid cash for my cars (and yes, sometimes I drove some very "uncool" wheels". I waited till I had cash to purchase TV's, stereos, computers, new furniture, etc., etc.
That's a very strange concept to all too many people today. To actually pay cash for everything.
The home I live in currently was also paid for in cash. I have no debt at all, None, NADA, nothing. I also have a more than adequate monthly income, US Medicare with a Medigap policy that picks up 100% of my medical costs (except prescriptons, which are covered by another policy).
Initially, my savings were only $3.50 per month (I went from $78.00 to $85.00 per month. Then, when I went to $99.00 per month, my monthly savings amount went to $10.50 per month, and so on. Even those small amounts added up over time.
There is absolutely NO reason why anyone can't follow a similar program.
