Yes, the "guarded" part was interesting. Certainly writing details about a serious health problem in a semi-public forum made me guarded - cautious about what I wrote. I think I was pretty structured while writing the blog. Surprising to me was the part of "unconcerned with taking pleasure in life: you prefer activities with a purpose greater than just personal enjoyment." At first I thought that was far off... but actually I take enjoyment from working on creative projects and producing things. I find it hard to sit and do nothing. So I think there's something to this - different states of mind while writing led to different results which matched my personality somewhat.
Ya. I feel ya. I got virtually the same response when I submitted posts I had made about my own serious medical condition. I submitted what I thought was the real me but, could not agree with some of the points made... I think you are very right - differents states of mind and different writing pieces like from my blog vs. forum posting will lead to very different results!
