To succeed in life, people often need a person to coach them. Having a coach or someone to guide them towards their goal while holding them accountable increases the likelihood that the person will find their way to their desired result. This need for help in accomplishing goals has led to a business model that is rapidly expanding.
Coaching as a profession dates back to the 20th century. While Leland Bradford wrote on the topic of executive coaching in the 1930s and 1940s, coaching didn’t really take off until the 1970s when business executives began requesting help with their business goals.
