As long as I can remember, I have had this nagging feeling that I was supposed to do something. It was not that I had forgotten to do something. (Though I do.) (Often.) It was that I was supposed to do something; I just didn't know what.

And not just any something. Something Substantial. Something Significant. Maybe inventing something important like dwarf wheat or poptop cans. Or maybe, like the Scarecrow in the Wizard of Oz, by thinking some Great Thought such as:

Foolish hobgoblins have consistently little minds.

Or:

The little minds of fools have consistent hobgoblins.

Or:

The foolish minds of hobgoblins have little consistency.

I know there's a Great Thought in there somewhere...
