How to get my wisdom score to 18? | Ask MetaFilter:
"Relentless self-reflection, combined with placing your self in situations outside your normal experience.
A few years ago I sold almost everything I owned and went off to wander around the world alone. Among other things, I eventually realized that with my social circle constantly changing, I could get up every morning and decide who I wanted to be that day. Freed of the day to day inertia, I experienced many physical, social, and particularly spirtual things that simply would never had happened in my home environment.
Which isn't to say that I am any wiser for it, but I do have a far clearer concept of who I am and what I want than I ever have before."
