A life coach is a wellness professional that helps people to progress in their lives, whether personal or professional, to gain greater fulfilment. Life coaches help their clients to improve several aspects of their lives, such as careers, relationships, fitness levels, productivity and every aspect of their day-to-day lives. This ultimately has a positive effect on well-being and mental health in general. When we receive this kind of help and support, our self-esteem gets an immediate and positive boost.
