Stan Hinden from AARP shares six retirement mistakes he made throughout his life in addition to a pair of better choices. Here are some thoughts on three of those mistakes.

Thinking about retirement should come with the first paycheck, but Stan wasn’t considering the day he’d no longer have income. He didn’t think ahead. Will your pension (if you’re lucky enough to earn one) and Social Security cover your living expenses? Your company provides pension statements and the government sends a Social Security statement each year. You should be able to determine whether the funds available by the time you retire are enough to hold you over for several decades.

Chances are that it’s not enough. Perhaps this is enough of an incentive to get people to start thinking about how they’re going support their expenses. Sure, there’s always a risk that you won’t live long enough to retirement, and money exists to be used to enjoy the time you do have alive on the planet, but you should still think about what will happen in the not-so-remote chance you won’t get hit by a bus before you leave the workforce.

Stan thought he could handle everything. While he didn’t see the need for a financial planner, he visited professionals for medical attention. He regrets not seeing a financial professional. Don’t fly solo, get help from people who are trained to help you. The general feeling is that fee-only financial planners are where it’s at. They are likely to look out for your interest while other financial advisors want to line their own pocketbooks.

Like 80% of the world, Stan believed he was smarter than average. He thought he could outguess the market and time trades in a way that would provide the most benefit. He ended up selling a certain fund at an extreme low point—he chickened out—and missed a sizable gain over the next few years. If he were to do it again (wouldn’t we all like to change decisions?) he would buy and hold and keep his emotions home.

Where do I stand and am I making these mistakes? I am thinking about my retirement, but I wasn’t when I first entered the workforce 7 years ago. I was working at a non-profit organization for little pay and no benefits—certainly no retirement program. I was spending more than I earned just to pay rent and commute to the job. Although I’d like to be working in non-profit, I couldn’t continue in that direction. My 401(k) is now doing fine around $25,000, although it’s taken a hit due to the stock market lately.

I have no financial planner. Right now, I don’t have enough assets for it to be worth it, but when I start a family, this will be a top order of business. On the positive side, I don’t try to time the market. My money is all in index funds (except for about $50 invested through ShareBuilder) and I plan on letting the funds sit for a long time.
