Oprah Winfrey and Richard Branson have used mind coaches to accelerate their success, as have many other celebrities. Even hard-rocking band Metallica used a "personal enhancement coach" to help them through a rocky patch.Demand for coaches is soaring, with the International Coaching Federation seeing a 50% rise in membership in the past five years.Now, a "happiness expert" claims a mind coach could be the missing link between us and success - in work, money and love.Paul Dolan, a scientist at the London School of Economics and author of Happiness By Design, says: "Just as people have for years been employing personal trainers to help them get fit and lose weight, so too achieving goals can be accelerated by using an adviser or coach to apply similar principles to success in life."The difficulty we have in sticking to goals, he suggests, is due to the brain having two systems."System one governs the fast, automatic processes we do without even knowing we're doing them and system two, the slow, deliberate moves we make thanks to having rationally thought about them," explains Dolan.The trouble is, "You're making 10000 decisions each day and most of those are made for you automatically by your system one brain. A coach can intervene on these automatic 'habit loops' and give you the small, practical, daily strategies to create new ones, as well as the feedback on when you're getting closer to achieving your goals. Feedback is key."Most people know they need to set challenging but achievable goals and then break them down into bite-sized chunks."But we also need feedback on the small achievements," says Dolan. "So, just as a personal trainer might count up your reps on bicep curls from one to five and then backwards from 10, a mind coach can help you achieve a goal by giving you feedback on small percentages achieved, for example when you've reached 10% of the goal ... and then count down with 50% to go and so on.""Coaching is about the future, whereas the focus on psychotherapy is often on resolving difficulties arising from the past," says Magdalena M Nook, CEO of the International Coaching Federation. ..
