Albert Einstein said: "I never think about the future. It comes soon enough." Clever, sure, but Einstein wasn't planning for retirement.

The fact that retirement looms is the reason to get thinking now. Yet if you don't have a plan, you're not the only one. According to a MetLife Survey, 66% of baby boomers worry about retirement security. According to the SEC, two-thirds of Americans don't believe they know enough to make their own financial decisions.

But here's the thing: You can make your own financial decisions. And it's never too late.

Get organized
There are three keys to getting started:

  1. Pay off high-interest consumer debt.
  2. Live below your means.
  3. Be smart with your money.

The key, of course, is the third step: Be smart with your money. This means regularly saving and investing, allocating assets efficiently, and avoiding fees and taxes. There's no way to build your own financial empire if all of your funds are helping to build someone else's.

Get going
Don't have an individual retirement account (IRA)? That's fine -- but you should start one today. An IRA is the best way to make tax-deductible contributions toward retirement. It's also the best way to enjoy the gains tax-deferred. In other words, you can pay for the future without paying Uncle Sam.

Let's say you haven't saved a lick yet but decide to open an IRA today. To max out in 2007, you need to contribute only $333.33 per month. That might be difficult, but you can do it. A simple goal is to try to save more than you spend. After 2008, you can max out by contributing $416.67 per month. That's not much more, but it can make a world of difference. Plus, you will have done so well in 2007 that the increased savings will be a walk in the park!

If you start this plan today, you could have a tax-deferred nest egg of more than $80,000 by 2016. That's not great, but it's not bad, either. And if you have 10 more years until retirement and let that money continue to compound annually (without any additional contributions), you could have more than $200,000. If you continue to make those $416.67 monthly contributions, 20 years of savings and investing will give you the tidy sum of $300,000. Now we're talking!

Get smart
These calculations are based on earning the market's historical 10% annual return. You can do that by investing in a low-cost index fund. But beware: Not all index funds are the same.

Morgan Stanley's S&P 500 index tracker is roughly six times as expensive as its peers, which hold the same basket of stocks! These stocks include 3M (NYSE:MMM), Apple Computer (NASDAQ:AAPL), Cisco Systems (NASDAQ:CSCO), Google (NASDAQ:GOOG), Time Warner (NYSE:TWX), and other giants.

If you inadvertently hold the wrong index fund for 20 years, you could be out more than $20,000 in the scenario above. That's a costly mistake that you'll do well to avoid.

Do better
You can hope to do even better than the market's historical return if you allocate your assets intelligently and make some smart stock picks along the way.
