What I was trying to say...

I have found that when I have written something of any length (I mean words) I will very likely shift to another seat to read it back. Shifting from my persona as writer to that of reader. I think this is quite a common practice.

I also find that if I have written a song than, until I have sung it to other people, I am unlikely to write another one. (There are exceptions where a bunch of songs around some common theme come along in parallel.)
