Think about how much intellectual capital is lost when an experienced employee leaves a company. That person has developed a knowledge base, the expertise, and the stature to work as a high-level professional.
If you have been fortunate enough to hold such a career position, chances are your value in the marketplace can apply to a potentially lucrative, flexible second career: coaching or consulting. Writing for Harvard Business Review, Dorie Clark, author of the book Reinventing You, offers some excellent advice in "How to Become a Coach or Consultant After You Retire."
Clark recommends giving yourself plenty of time to make the transition from your full-time job to becoming self-employed -- as much as a year or more. She recommends conducting a self-assessment skills analysis to determine where you need to improve.
Clark says it's a good idea to concentrate early efforts on recruiting clients, even if some are volunteer efforts: "To gain experience as a coach or consultant," writes Clark, "take on a few volunteer clients on the side, while you’re still employed, in exchange for testimonials and future referrals (assuming it’s a good experience)." She also recommends a sensible attitude toward marketing: "Recognize the goal of your marketing," Clark writes, "[is] establishing a baseline of credibility for when a potential client checks you out." And taking a break between your job and starting a consulting practice is not a bad idea, either.
Coaching or consulting is not for everyone, but it is certainly a viable option if you have both the depth of experience and the desire to run your own show.
