It's probably also smart to keep some money in cash to invest it. But I would resist at all costs taking a lump-sum distribution because the tendency is to spend out too fast in the early years of your retirement. The advice of professionals is to take out no more than 5% per year and that will give you 20 years of distributions, and at your age, 55, you probably have more than 20 years life expectancy.

The main problems are insufficient diversification and the failure to pick age-appropriate strategies - that is, more aggressive when you're younger, and more conservative when you approach retirement. But even then you have to invest for growth.

The children of baby boomers should take very seriously the consequences for them of the inadequate funding for them of the baby boomer generation. This is a huge economic problem for the nation, not just for individuals or individual families. Think about it for a minute - if retirees become 20% of our population and their purchasing power falls below what has been normal for retirees in the past, one important engine driving our economy will be diminished.

I personally make sure that some of my investments are in foreign securities or in international commodity portfolios that are independent of the US dollar. But that's a personal preference. I do not invest in currencies because it's so complicated and so risky. I would not attempt that without excellent professional help.

It's usually much easier for people with professional skills to find work for themselves or even possibly to continue with their old employer, but on a part-time basis. Some labor economists predict that in about five years there will be a labor shortage in the United States and that demand for retirees to work part-time will grow naturally. I don't know if that's true or just wishful predicting.

In Western Europe, most countries have variations of the lifetime pension system for most workers so they are keeping the system that we are walking away from. By comparison, 50% of the American workforce is not offered any retirement plan by their employers. And of those who are offered a plan, roughly 25% do not choose to join. In other words, everything is voluntary, and that's one of the reasons our results are so perilous for most people.

The most common mistakes were investing in money market funds by people who were so scared at the prospect of managing their own funds that they picked the most conservative option, and their investments did not keep up with inflation. The second major mistake was being too heavily invested in their own company's stock, and buying when it was high and there was a lot of optimism about the company, and then having to sell it low when the company got in trouble.
