I generally take "[h]andling your own problems" to mean taking responsibility for your own problems.

I'm seeing a lot of agreement in this thread, though. Healthy, deep relationships with family and close friends are important to keep you grounded, and therapy can help everyone. Many seemingly desirable positions of status that men and women strive for involve incredible amounts of stress, and people naturally have differing levels of stress tolerance, so at some point self-knowledge becomes very valuable. Having good people around you is a great way to build that self-knowledge.
