What is the definition of life coaching?
The first use of the term "coach" in connection with an instructor or trainer arose around 1830 in Oxford University slang for a tutor who "carried" a student through an exam. The word "coaching" thus identified a process used to transport people from where they are to where they want to be.
The first use of the term in relation to sports came in 1861

So much to the definition coming from sports, actually it’s the other way around.
