Tugboats and trains perform distinct and separate functions in real life. Tugboats operate on water. Their mission is to push, nudge and help direct the barges and large vessels that cannot turn very precisely in the confined areas of a harbor. Trains are designed to pull and transport heavy loads over steel rails to a specific destination.
In business, to be successful, you must have both the tugboat and train. You need people who are tugboats. And you need people who are trains. As a personal business coach in Houston and The Woodlands, I have seen successful businesses. the necessity for both over a forty-year career in business.
