We must learn any specific hunting/gathering skills from role models while growing up. We even learn from others what goals are worth achieving. We are right now learning from each other how to think about our goals and problems.

This is not the first time humans have the choice of picking their goals. Even on an evolutionary scale we have always had cultural institutions to guide us with that (and/or exploit us). For example we have thousands of years of stories about worthy and unworthy goals.
