Idea Conflict

[caesar13]

I have read the book Mastery by Robert Greene. Nice one.

Now I am reading the book "So Good They Can't Ignore You" (written b y Cal Newport) in which the author is against the passion mindset and encourages the craftsman mindset. I feel all along the book there's a conflict lurking in my mind. Do I now go towards finding my life's calling or do what I can to make myself valuable - to be in the path of giving the world something valuable?

Readers who have read boths the books can understand my confusion.
