I think one has to accept that some days are more productive others less (or not at all). That is why hacking is a creative art form and not a data entry job. The more you freak out about it the harder it gets getting back into flow.

Personally, if I'm absolutely stuck at how to approach a coding problem, I simply start coding the dumbest solution for it, violating every rule in the book just to move forward. Usually that is enough to get the ball rolling and with today's tools, refactoring the code afterwards does not take very long at all.
