The following 3 scenarios as mentioned by Cal Newport in his book So Good They Can’t Ignore You, may not be the most favorable ones to adopt a CRAFTSMAN MINDSET & can lead to detrimental results.

1. The job presents few opportunities to distinguish yourself by developing relevant skills that are rare and valuable.
2. The job focuses on something you think is useless or perhaps even actively bad for the world.
3. The job forces you to work with people you really dislike.

Thus being aware of these scenarios can help us avoid pitfalls while trying to force fit a CRAFTSMAN MINDSET.
