I enjoyed this video of Carol Quinn and she taught me about motivating the unmotivated. She explained that the middle performers need help with figuring out their true potential. Carol explains or deal with obstacles is by teaching the people to achieve the right outcome.
The highly motivated people always stand out; they are the ones always wanting to lend a hand. The ones going that extra mile and always making sure things are right. I would look for many achievements, awards, extra certifications, community service and any type of local clubs or boards.
