Most people assume that coaches require field-specific knowledge in order to work with the client, as is with the case of mentors, trainers and consultants (i.e. they advise the client on what to do based on prior experience).
Coaches, however, do not advise.
Coaches enable a client’s self-discovery and empower them by drawing from their own creativity and resourcefulness to cause their results, thereby increasing their client’s ability, self-confidence and self-esteem in the process. Because clients are able to generate their own solutions and actions, they can repeat their success in the future.
