Ask HN: Lisp programmers - do you experience occasional code blindness?

We all have good days and bad days. That applies to coding and may even be exaggerated there. At least my observation has been that the difference between a productive day and a not so productive one can be almost an order of magnitude.

In most languages I will still write code on the not so good days, just not as much. With Lisp however, on the bad days, I don't write a single line of code. And if I do, I discard it the next day. Do you have that same problem? If yes, any theories on why that might be?
