Answer:
1. I think that the statement: "an individual is not cut for any vocation" is very much ridiculous I disagree with this statement, because if an individual really doesn't deserve a vocation then why did God give it to them in the first place? God thinks they deserve it that is why he gave it to them, so no one has the right to say that an individual does not deserve a vocation.
2. Because it provides a realistic and effective shortcut in focusing career exploration.
I'm not sure if my answers are right, but I hope this helps you.
