When I was feeling treacherously overwhelmed and unmotivated with my college classes, one of my writing mentors/bosses (shout out Jeff Griesch) would tell me, "There's only one thing you have to do, and it's start. Once you've started you've already won. "
This quote still gets me going today, at work and especially with this site.
So even if you have to start a few handfuls of times, even if you're just starting again and again, you've already won.
(Case in point - you're reading this on my finished site. took a lot of starts but we in this bitch!)
