What is a coach?
The word started as a description of a method of transportation. Think stagecoach, or motorcoach (more commonly a "bus" here in the U.S.)
Turns out it's the same in business, as in athletics: a coach is someone who can take you where you want to go.
They don't do the work for you.
But they should be helping you reach your destination in ways you couldn't do on your own.
Of course, deciding where you want to go ... that's up to you.
All the best,
A.
