There are the inspirers, and then there are the anti-inspirers. There are those who validate the whole idea of creativity, and sharing it with others, and there are those who invalidate the whole idea of creativity and sharing.
It's best seek out the inspirers, and try to avoid the anti-inspirers. But once in awhile, you get pulled into the vortex of the anti-inspirer. And then it's all invalidation and bad feeling. Kind of makes you want to just go out to the forest, sit under a tree and clear your mind. To be silent, and just breathe.
So, yes, I guess in that respect the anti-inspirer can do you a great service too...
