Perhaps it is.
And yes, my stubble is exceptional.
I don't think less of anyone based on their relative strengths there, and I fully admit that there are those with expertise and experience that I do not have (and am always fascinated to learn about). But understand I was in gifted schools from childhood, started university at 15 (maybe I had turned 16 I don't remember) and was speaking in scholarly conferences by 23. I was classed as a genius at 14 years old. Finding a genuine challenge is rare to me, but I know that I am no more capable than anyone else, just that most people don't bother to apply themselves to the limits of their abilities (myself included, most of the time). I would say that my friends are my friends because I can see them as equals - we each challenge and entertain each other in our own ways with our unique talents and personalities, but sadly I don't see my friends as often as I'd like.
That being said, I don't need to be challenged all the time, no one does. However, in my current line of work I have no challenge whatsoever, and need to seek it out. I apologize if that comes off as conceited. I've been around here long enough to know that there are a great number of regular posters who are capable of providing and a great many more who I believe would be if they considered the origin of their own stances on things.
Unrelated though, your use of "isn't it?" to your statement I found interesting. Turning the statement that I am conceited into a question seeking agreement is much less harsh, but still gets the point across. The Japanese do the same all the time even with indisputable statements by ending their sentences with 'desu ne?' I had always thought that rather odd, but here is a perfect example of the same reasoning behind one in English. I wonder if the Japanese are truly that shy or if it is something that has become just accepted not to put oneself forward. Was your statement indisputable? Probably.
