Are Ambitious Objectives Really Beneficial?

Christian: I don't actually agree with necessarily agree with everything that Kenneth says, or at least I want some more clarification because there's like certain things in the book. He does of course say that for modest pursuits for small goals where you can see the light at the end of the tunnel these objectives can work and they do work and we shouldn't stop using them. But in my experience, I think that ambitious objectives can be really beneficial.
