It may be possible to figure it all out on your own, but that's foolish and time consuming. The world is full of people with wisdom. Taking guidance from the wrong people, however, can be disastrous. More wisdom equals more life, more pleasure, and more meaning. It's the ultimate value.
People have some idea that there's nothing to learn outside of a university.
This attitude is destructive because it stops us from learning the many bits and pieces of wisdom that are available. If you want to get the most out of living you have to believe that wisdom is available. He who learns from all people. You don't have to always be waiting around for that one incredible piece of wisdom which will dramatically change your life. Even a collection of smaller, less outstanding pieces of wisdom can make a significant impact.
