Frugal retirees: Go ahead, spend your money
Consider your cash flow
Many of us grew up believing we should never touch our principal. And while that philosophy can serve us well during our working and saving-for-retirement years, it can also become so ingrained that it's hard to change. So as a first step, you might consider taking some of your dividends and interest in cash rather than reinvesting them -- that is, before they get added to your principal and become off-limits.
If you don't already have one, it's easy to set up a sweep account at a brokerage firm; it will automatically deposit your dividends and interest into a money market account, which you can draw on as needed.
