Karen Wimbish, head of retail retirement at Wells Fargo discusses her 16 years in the securities business.

I grew up in the Hampton Roads area of Virginia with five siblings. I had a high grade point average, which at the time could translate into a high Civil Service score. I entered the Civil Service and worked at NASA in the aircraft wing design group at Langley Air Force Base for three summers.

When I graduated from the University of Richmond with a degree in math and economics, NASA offered me a job. My parents were horrified when I turned it down because it paid double what other graduates were getting. But I wanted to be around people in a less isolating role. I entered a management training program in retail banking with United Virginia Bank, which became SunTrust, and worked in credit analysis.

About every two years, I changed jobs at the bank. If there's a position that will expand your toolkit, even if it's a lateral or a short-term assignment, you should consider it. By moving around, I managed projects, was responsible for profit-and-loss centers, and helped turn around problem businesses.

In September 1987, I became a commercial account manager with a loan portfolio that included manufacturing and insurance companies concentrated in broker-dealers. The next month, the market crashed and the whole industry was awash in margin calls. My clients were faced with millions in outstanding loans. It was a baptism by fire, and no one could value their securities held as collateral.

In 1996, I moved from banking to brokerage when I joined Wheat First Securities, a predecessor to Wells Fargo Advisors. I spent four years in asset management, leading the high-net-worth and institutional relationship management group.

Next, I moved to the retail brokerage at Wachovia, followed by the Latin America Group, a real stretch assignment. We incorporated nine Latin American offices into our firm. I learned that if I could figure out those operations, I could figure out anything.

I've worked for the same firm under four different names for the last 16 years, starting with Wheat First. In 2010, I was promoted to my present position.

I love my job because retirement is on everyone's mind. When I appeared on TV, the makeup artist, hairstylist, and my production escort all asked me about their retirements. They ranged in age from 20-something to 50-something.

Our industry has been focused on accumulation and total return, but that's shifting. For the first time, boomers are spending principal. Retirement income is the next frontier.

Recently, I achieved a dream on my bucket list — visiting Machu Picchu in Peru, where farmers still till the fields by hand. It puts things in perspective. Despite our economic and social challenges, we're very fortunate in this country.
