When I find myself in times of trouble, the Survival Guide says to me:

When the deadline is approaching, it’s still important not to panic. If things feel confusing, take a break. Even five minutes will do. Get some fresh air, take another shower. Your head keeps working even though you’re not looking at the problem. Since it’s all your code, you should be able to figure out the problem, but banging your head to the keyboard won’t help anything.

The most important bit is not to give up.

Remember to leave some time for packaging and final testing.

Also, it’s entertaining to watch all this progress on the blog as you code – so keep ’em coming! Best of luck in these final 12 11 hours…
