From what I've read of some of your posts on here, most of your writing is just a lot of fluff, and intellectual feather strutting, without much substance.
If you feel you've lost your "edge", might I suggest that perhaps you never had any "edge" to begin with, and that maybe you where only being deceived by your own ego. I'm not trying to be rude or condescending at all. We all need a reality check from time to time, maybe this "losing your edge" stuff is part of yours.
