What if the thing you once called inspiration was simply your mind distracting you from your real work and purpose?
What if real inspiration turns out to be something else entirely?
Well, perhaps not entirely. Consider, how a stream that flows into a river is now only part of the river. Similarly, the old inspiration is part of, but much smaller than, the new inspiration.
The two things can be so different as to not seem much alike at all.
Be glad, in the end, that you came to the river. Know that the river will lead you to other rivers, lakes, eventually the ocean. There are depths there, things which today you don't know, but may yet be revealed to you.
