SO to answer your original question. Yes, in that I see having a huge brain, capable of expressing and thinking the sorts of things yourself (Vox) and Voyle have been talking about must at times, be exhausting.
I'm pleased to be able to think about things and see things simply, just because I am simple and stupid and thick.. if my kids lives depended on it, I could not explain what the two of you are talking about.. .whooosh .. right over my head... and whilst at times I have wished to be more brainy than I am, so that I could accomplish more, to be burdened with this kind of thinking would be the end of me within days or even hours.
The lives I appreciate the most are those laid down for others, those who have paved the way so others may have freedom, liberty, a voice. 'If I have seen further it is by standing on the shoulders of giants' ... It is these 'giants' that I look too.. attain to be, if only for a second to one person..
I have had glimpses of that in my life so far, one in particular when something I did for person A, directly effected person B without me even knowing it.... and it was only years later when person B approached me and shook my hand and thanked me, that I had the slightest clue that my actions had helped turn his life around.
Being where I am has made me look at this 'moments', and realize that there are people out there that I have helped, have guided, and should I really be 'giving in' just yet....
Not quite what the two of you have been talking about, but my take. :)
