Your Fragile Mind/Your Strong Mind

I read a blog by Tim Ferris called the Four Hour Work Week blog.  He has an article about depression and the impression that word or diagnosis might do to your self esteem.  Click here to go to the article.  When I spend too much time contemplating dysthymia I naturally become more depressed.  Sometimes so depressed that I can actually feel it in my chest cavity.  At my work I took a class on “People Styles.”  It mentioned that I was a certain type of person, as amiable, when I was positive that I was a different type, a driver.  It turns out that I actually operate at both, naturally I am amiable but under stress I become a dictator.  I was stressed so often that I thought I could only operate as a driver.  When the suggestion was made that I was amiable, I took it to heart and just let things happen.  Very reactive to work, instead of proactive.  My work really suffered because I was not on top of things.  Just reacting.  I am currently digging myself out of that hole.  A very deep and challenging hole.  So, how do I “think” about being what I want to be?  To be a more powerful me, a me that isn’t afraid, a joyful me?  Any ideas?
