Marketing vs Mentoring

Is there a difference between marketing and mentoring?
Yes and no. Yes, if you look in the dictionary and no if you are working with a client.
When marketing a business you need to know how the business works, the goals and the people in the business. For me, the two go hand in hand. When I'm asked to do marketing for a client, I immediately ask them where they want to be in a year and what the end goal is. Are they after more sales, more clients, more time to themselves etc. No two businesses can be marketed the same way. 
Marketing can mean many different things to many different people.
