It might sound counter intuitive but; Humility. The knowledge that I am just a man, with faults and fears, and that there are things in this world far greater than myself. There are powers far greater than mine that control things around me. Typically people think of spiritual power and put their faith in religious beliefs, but it could also be the power of nature, or friendship, community or anything else. It's only by realizing how powerless I am over so many aspects of my life that gives me the strength and courage to recognize, seek out and accept help. Otherwise there is a tendency to "man up" and fix everything myself without the crucial step of understanding that either I didn't create the problem by myself or I lack the physical, spiritual or emotional tools to fix it myself.
