Indeed there was and that is the idea that when we write - if we really want to touch people with our writing - we need to write first and foremost for ourselves. Because there is something that needs to come out and be immortalized, even if only for our own benefit.
I'm sure you've felt the shift that takes place when actually putting ideas to paper (or bytes in this case). There is something transformative that occurs when we write our thoughts down. There is also a fulfillment that can occur, simply by releasing our thoughts into the universe, rather than keeping them wholly our own.
As to the question of retreat. If it's necessary and productive then yes by all means retreat. If nothing else you will put yourself into the stillness that will allow you the time to consider whether the retreat is actually necessary or just a way of dodging what IS necessary.
