If you jump off a diving board into a pool and no one is around to hear it, does it make a sound?” This philosophical question doesn’t seem to have an answer. I mean, there is only a sound if someone is there to perceive the sound waves, right?
Your message, your story, your speech, and your books are the same way.
The sound they make is—dare I say it—irrelevant, if there is no one there to watch you, hear you, or read you.
It might be that your audience isn’t smart enough, caring enough, attentive enough, with-it enough or generous enough to understand and appreciate you.
Or you’re wrapped up in “the thing.” Spending so much time reading, editing, practicing, and perfecting for your “someday” audience that you lose sight of the fact that you don’t have an audience … yet.
Or it might be that you’re not good enough (yet).
If you’re assuming it’s one of these, try out the other one for a while.
