I think there are certain people who are meant to serve and others that are not and it is your job to work as hard as possible to find people who you are meant to serve. And I believe you will find them when you show up fully self-expressed. Most marketing books are tactical, so they focus on quick solution, for example, just do this or do that. This is OK if you are looking for a quick fix, but this does not teach you how to build trust and credibility, or how to price your products or how to have simple sales conversations which is required if you are doing pay per click advertising.
