Creatives, let’s use the word “Mastery”

I am working with a study group whose members are all board members from I Heart Art here in Portland.  What a great group of talented creatives!  We had a great discussion last week about the way that the concept of “expert” is now being co-opted by people who only want to make money by claiming expertise when it may not be warranted.  I have been thinking a lot about that conversation and I think the word we creatives should use is “mastery.”  What we are doing as we move confidently into our unique niche, is claiming our mastery in whatever field we are in.  I think this word better describes what is happening and is easier to say.  What do you think?
