If you don't have a clear idea of what you want to do, start by evaluating your existing position. Make a list of everything you love and hate about your current job. Use those likes and dislikes to form criteria for a new career. Look for opportunities that feature the things you love but not the things you hate. For instance, if you love your job because of your relationship with your clients, look for jobs that focus on customer service. Or, if you love being the expert and sharing your knowledge, teaching is a possibility.

Also think about what you do in your spare time. What do you enjoy doing most? What is it about these activities that makes them enjoyable? If you love dogs, consider starting a boarding, grooming or training business. If you practice yoga, find out what it would take to become an instructor. Brainstorm ways you can make a career out of your passions the way that the Princes did with food.

2. Leverage your strengths: What do you do well?

For 24 years, Norman Daoust worked in corporate IT roles, except during a sabbatical when he focused on his music. Daoust plays fretted instruments-the guitar, electric bass, banjo and mandolin. After three years of trying to make a living as a musician he decided to return to corporate IT, only to remember exactly why he left before: the inability of large, bureaucratic organizations to embrace and manage change. He had to get out, but instead of going back to music, he opted for consulting in his area of expertise, information modeling and systems integration. He prepared for that transition by participating in several consulting workshops. When he was laid off from his corporate job in 2001, he took the leap. Seven years later he has built a successful consulting practice with many clients and the freedom to make his own schedule, including time for his music.

A great tool you can use to identify your strengths is the book StrengthsFinder 2.0. When you buy it, you get a code to take the StrengthsFinder assessment online at no additional cost.

3. Assess your options: What could you do that reflects your interests and leverages your strengths?

Tom McGoldrick performed many roles during his 30 years in IT: systems programmer, project manager, department manager and senior vice president. He left IT in 2002 during a downsizing. When he stepped back to look at his life, he realized how much his career had taken him away from his family. He and his wife Sue Ann decided to look into running their own business.

They considered more than 1,200 different businesses and eventually narrowed the list down to six. One option was inspired by their beloved pet Labrador retriever, Apollo, who had a champion bloodline. They considered breeding dogs, but further research showed they couldn't make a living at it. When Apollo unexpectedly died, they looked for a burial/cremation facility that would provide Apollo with the honor and respect the McGoldricks felt he deserved. They discovered Paws in Heaven and were very pleased with the care and attention Apollo received there.

In 2003, the owners of Paws in Heaven decided to retire, and the McGoldricks bought the business. Tom McGoldrick recognized that the business savvy, technical knowledge and relationship-building skills he had honed over the course of his career in IT would lend themselves well to running and growing their new business. Paws in Heaven perfectly combines McGoldrick's love for animals with his business and technical acumen.
