I ran across Kevin Eikenberry's site about a year ago. Kevin – the Chief Potential Officer of the Kevin Eikenberry Group – works to help organizations reach their full potential. His site is tailored to adults, yet I find it inspiring. Divided into a number of categories, two caught my eye: teamwork and creativity. His posts (and the fact that he's a Jimmy Buffett fan) keep me coming back for inspiration.
Kevin is today's stop on the Team Challenges virtual book tour, where he notes that the activities in Team Challenges are just as well suited to adult team leaders as they are to kids.
