Q: I'm a baby boomer and concerned about retirement. I thought I could depend on my house and 401k to supplement Social Security, but after the past four years I'm not so sure. I'm only 50, so I probably can recover. Can you help me get to a comfortable retirement?

A: You're right to be concerned about your retirement. It's very likely that the rules for retirement will be rewritten in the next 10 years. The concept that everyone retires in their mid-60s and never works again is obsolete. Recognizing that now and making adjustments could make a big difference in your future lifestyle.

It's widely agreed that the Social Security trust fund is running out of money. If the current funding and payout system stays the same, Social Security's reserves will be exhausted in 2033, according to the Social Security Administration. After that, taxes will support only about 75% of scheduled benefits.

So unless taxes are raised on younger workers, your benefits will be cut. That means a greater reliance on what you've managed to accumulate in private pension plans, 401ks, individual retirement accounts and equity in your home.

There's no one single thing that you can do to guarantee a comfortable retirement. But there are a number of lifestyle choices and decisions that you can make that will make a big difference in building a retirement nest egg.

Do remember that $1 today will be worth more at retirement. Every dollar you save now will benefit from the multiplier effect of compound interest. Depending on how soon you need it, that dollar could be multiplied two, four or even eight times.

Don't let pride of ownership lure you into buying overly expensive autos or trading up too frequently. The salesperson always wants to put you into a new ride. Don't listen. Better to buy a vehicle with lower status and keep it until repairs exceed the value of the car.

Don't let your children's or grandchildren's college deplete your retirement savings. Yes, you rightfully believe in education and want your offspring to have the greatest range of life choices. But, by not helping them pay for an overly expensive school you're doing them a favor. You're forcing them to consider both the cost and benefit of their degree choice. They're less likely to choose an unmarketable major. A bad major could haunt them for years.

Don't let "living large" today cause you to live very small later. We're awash in premium products. Everything from breakfast cereals to the homes we live in. And luxury products are much more expensive than the more-typical choices. All those premium choices add up and deplete your savings, too.

Don't enable others in their financial bad behavior. We all want to help friends and neighbors who have been hurt by the recession. And we should help when we can. But, if we're giving or lending money to someone who's not making an effort to bring their expenses in line with income, we're just delaying the inevitable. Sooner or later they'll run out of money, both theirs and ours.

Don't overreach trying to make up for recent losses. Your home may have lost 30% of its market value in the recession. It will likely be decades before you see those prices again. Don't try to try to adjust your investments to make that up quickly. You'll be taking on unnecessary risk. You're still young enough to invest for the long haul.

Don't panic over changes in your retirement portfolio. Markets will move up and down. After taking some losses, you may feel tempted to pull everything out. Don't do it. Barring bad fortune, you can expect to live into your 80s. That leaves plenty of time for a balanced portfolio to recover losses.

Don't underestimate your target. One rough tool used by planners is that you can safely take 5% of your savings each year. So for every $10,000 in income you want, you'll need to save $200,000.

Don't assume a traditional retirement. Begin to consider what your retirement might look like. Many boomers are choosing to continue to work part time or to start entirely different careers. In some cases, they're beginning to lay the foundation now. There will be more options available for boomers as they get into their 60s.

Do take a look at your lifestyle and behaviors to see what might be keeping you from preparing for a comfortable retirement. Saving for retirement isn't an impossible challenge, even if you've taken a hit in the most recent recession. The trick is to remember that it's not a sprint -- it's a marathon. Make a little progress every month and you'll cover a lot of ground in 10 or more years!
