"Coaching" is a concept that originated in the corporate world of human resources, team building & leadership, and has developed a wider application in the realms of personal growth, job transition or new venture startup, & creativity.
Of course, many artists hum along very well on their own, finding their muse and their audience, never missing a beat. But there are critical phases (new beginnings, transitions, inquiry) where a coach can help things along more effectively than a new class, a gallery, a cohort or counselor.
A coach's only agenda is your progress, your discoveries, your decisions, your goals and your clear sailing towards them. They home in on your most heartfelt ambition and say things like, "Let's take a closer look at this thought that's stopping you," or, "What if we did some laser surgery on these obstacles in your way?" or "What would it look like if you were to think really, really big?" and "How can we manage the anxiety this will cause?" They challenge you, provide tech support & feedback, and leave you completely in charge.
I think coaching is well-suited to artists and other creative people because there's never an "off the shelf" solution. Each session is tailor-made to your own circumstances.
