I find myself stuck in those circumstances of anylsis paralysis. Being concious of it, such as after reading this article, helps you say "feck it, just do it somehow".
The stats coming from Google Analytics, Adwords, and other advertising data still overwhelms me though.
I find that having a day job and other life distractions actually helps with this a lot. I spend a lot of the day thinking things through so that by the time I get to having the time to do something I'm ready to actually do it.
