Coaching includes several principles from sports coaching, like teamwork, going for the goal, being your best. Coaches focus on strengthening their clients' skills, not on helping them beat the other team. A best friend is wonderful to have. Have both - a best friend and a coach. Simply put, it is that we humans are great, that we're all discovering what we really want, and that we can get what we want faster and more easily by having a coach who's been there and who can help us.
People hire a coach because They want more.
They want to grow. They want to do things more easily. You take more effective and focused actions immediately. You stop putting up with what is dragging you down. You create momentum so that it's easier to get results.
