Quote from the article:
"In other words, if you have saved just $25,000 -- and remember, that describes about half of all workers -- you are less than 2 percent of the way toward your goal. Your future definitely doesn't include cable."
My situation is that I have diligently saved 12-14% of everything I've ever earned, in the 12 years I've been in the US, into a 401K.
Sadly in those twelve years, I've endured 2% mutual fund fees and two market crashes, all of which hit my savings pretty hard. In fact, I lost money after inflation is taken into account.
So at 42, I basically need to build something I can sell and assure myself of some income over a reasonable time period. In my case as an engineer, I need to build a software company.
I also need to stay healthy, live as cheaply as possible, and shed as many expenses as possible once I get nearer to retirement. Boat or RV living looks like a great way to do that. Certainly paying the fixed costs of a house or apartment is going to be a killer for those on a small income.
