Top 5 contributing

I have worked on the webinar How to Feel Better.  After writing the top 5 priorities in “Constraint”, Brooke explains about her top 5 contributing. I have understood this as what she brings to succeed in the top 5 priorities or in her business.  But I am not sure of this meaning.

I am working on creating my business (not a coaching business). It is ok for my priorities but for my contributing : are they my strength, or what I write (ebook, blog or something else for example)?

I thank you in advance for your reply.
