Boy. This is a tough one. What helps with sustaining motivation to write for your blog? I find it has very little to do with a personal philosophy. “Just do it for fun. Do it to explore your interests and maybe gain some contacts along the way.” Sure, it’s a suitable enough premise. More than that though? I find it’s the habit itself that propels you to be productive. You find it has become a habit when you don’t have access to make a post, etc. Like any habit, it will sustain itself with very little conscious effort on your part. But if the goal is to sustain motivation, then the logical extension of that is to simply preserve through whatever means possible until it becomes habit.
