-- If you don't have a 401(k) or similar plan, contribute to a traditional or Roth IRA, and make catch-up contributions if you're eligible.

-- When you get a raise, save it in a personal taxable account or increase the percentage you put in your 401(k).

-- Put all or part of an annual bonus toward your retirement.

-- Invest your tax refund in your IRA.

Even in volatile times, retirement accounts offer the benefit of tax-deferred compounding. This gives you greater growth potential in the long run. If you're uncomfortable in the stock market, put new money into more conservative vehicles such as CDs or a savings account.

6. Rethink Your Retirement Options. Now's the time to think creatively about the way you might retire. For instance, you could:

-- Spend less in retirement. Ideally, you should plan for as much income in retirement as you have now, but you might get by on less if you've paid off your mortgage and eliminated debt.

-- Postpone retirement. You'll have more time to build your savings. You can also increase your potential Social Security benefit by waiting to receive payments (up to age 70).

-- Work part-time. This could mean extra income as well as a way to keep active and involved.

-- Tap into your home equity. If you own your home and you're 62 or older, a reverse mortgage may be an option (although watch out for fees and other requirements). Or downsize, and add the difference to your retirement nest egg.

My fundamental advice is to keep doing the right things in both good times and bad. That means making a genuine commitment to spending less and saving more -- and sticking to it whatever it takes. Today's uncertain economy might make it more difficult to achieve your retirement goals, but the good news is that the things you can do right now to achieve them have more to do with your own prudent management than the current economy. So be positive, and stay focused on the things you can control. You'll feel more comfortable about today -- and still be able to contemplate a relatively comfortable tomorrow.
