Have you ever experienced supreme confidence and a decided lack of it at the same time? It is a confusing to occupy, but it may be a common one. On the one hand one knows that they think and communicate well. On the other hand it seems as if there is little communication, and if one's thoughts are unconventional enough, that is to be expected, but long-term lack of communication undermines that confidence, brings instability to thought.
That is as it ought to be, if one lives through and with reason.
