If you don't invest, you won't have the money you need for a long, comfortable retirement. You won't have any extra cash to give your kids a helping hand, and you won't be able to survive the burden of an ill or dependent parent. You can decide today that you don't want to be in that situation tomorrow.

Research shows that 65 percent of women say they could find an extra $20 a week to save for retirement. That pocket change—it's less than $3 a day—works out to $1,040 a year. Let's say you managed that. You put the money away and you earned an 8 percent average annual return. If you retire at age 65, how much of a difference would it make in your life?
