I read once that in the course of a normal conversation, the talk will naturally come to a stall every twenty minutes. I guess you could say it sorta "re-boots" before it resumes again.
I've come to think this is also true of writing. It seems that I can only keep blogging for so long until I run out of things to say. When I've been reduced to posting photos I found online, it's time to quit for a while. I'm sure you can understand.
I suffer from a severely critical (even ruthless) Inner Critic. My Muse, on the other hand, is a total wimp. So, while I might be inspired to blog about something, the Critic takes the wind out of my sails. As if that's not enough, the Critic destroys my confidence and will to write!
I must admit that I've also been sidetracked by a volunteer project. Then, there's also the looming specter of approaching my 400th post. I don't know why I should find that intimidating, but it's like running toward a high hurdle. So, I'm backing up to take a hard run at it and get past 400 in a blaze of glory--or its meager bloggie equivalent!
