I'm 67 and retired.

I am interested in investing to earn at least 10% annually for income.

I have 580k to invest in something that can be considered fairly secure.

You can safely assume a 5% withdrawl rate from your account for starters, i.e., 29k per year. As your account continues to grow from it's investments, the $ amount will grow but the % the same. Search the posts for "max withdral rate" or "safe withdrawl rate", etc. This topic has been discussed in detail before.

Nothing is fairly secure except T-bills, CDs, etc. To insure outpacing inflation, you'll need to invest in stocks, and they carry risks. Even the "solid" comapanies can go sour. Read up on the mechanical screens here. May consider Foolish Four, Keystone, and Spark. Generally puts you in stocks that you've heard about and understand and shouldn't disappear over night.
