Life coaching is for those seeking to get somewhere where they are not. That can be from being happier, achieving balance between work and private life, to starting a new career or finally making that big change that you have been postponing for some time.
With responsibility, it's a very cleaver way to "make things finally happen". It consists in the use of an array of different tools that will help you to assess what you want from life and how to make the changes necessary for you to get there.
Life coaching is a broad subject and it is also the "birth place" of any other form of coaching that is done with sensibility and care.
