There are a lot of filmmakers in this world, which one of following do they each have?

Craftsmanship : know how other people do things
Talent : can devise new ways of doing things

Similarly, in the domain of word-making, there are:

Schobrick layer : receive, accumulate knowledge and struggle to keep up-to-date – it’s all about rules
Word maker : be at ease to organize and communicate his\her knowledge – less rules.
Rain Maker : generate knowledge out of nowhere– no rules.
