It's hard to do creative work when you're dead stuck. Like, just 'do it'. Even when you do push through, it feels alien and weird, as you leave the well-trodden ground of the doldrums, and enter uncharted territory.
There's no let's-play of your doing-it to explore before you decide to make it happen. There's no book with a table of contents to browse. It's just a big blank page, and that's scary. But if you push through, if you ship, you come out the other side in a beautiful and exciting place you've never seen before.
