People often underestimate how much money it takes to live in retirement.

I think early retirement is achievable for anyone who seriously wants to do it. It just may mean you have to cut back on how you are spending your money.

Some people don't have really expensive hobbies and just want to take one nice big vacation a year, especially if their families are nearby.

Retirement isn't what it used to be -- getting the gold watch, moving to Florida and playing golf, ... People want to stay in the work force to feel viable.

You have to be frugal and if you're not a saver now, it's going to be very difficult.

People can take this time to put money aside for retirement or to start a savings plan. But these are not sexy choices like buying that wide-screen TV.
