Fickleness and Discipline, Jedi Style

What is the difference between being fickle and being versatile ? or just being open-minded ?

…

As with Fickleness (being the quality of versatility taken to an inappropriate extreme), Discipline also must be conscientiously attended to. Let us become aware of circumstances and the needs of others when applying our Discipline so that this ‘quality’ does not turn into Stubbornness or Rigidity.

 

And as with all phenomenon, one can become the other (Fickleness <> Discipline).

—Benjamin-Alexandre, Temple of the Jedi Order
