People quite often ask me if everyone needs a mentor. The answer seems so easy to me (yes!) because it's actually right in front of our noses -- we just don't see it sometimes. Look closely at your circle of friends, family and other confidants. They are actually already mentoring you without you knowing.
Last summer, I received a call asking if I would be interested in being mentored by a former CEO of a Fortune 500 Company. A trusted colleague of mine had a friend who was starting a business called My Next Season, designed to transition executives and CEOs out of their corporate positions and into a meaningful retirement phase.
When talking about mentors, it's important to distinguish between those you choose for a specific reason and those who are essentially "life" advisors. I like to say that there are "mentors for a reason, mentors for a season and mentors for life." We all should have a number of them in each category at any one time.
