H is for Help. When things have gone south and you don't know what to do with a project you're working on, step back and ask for help from other writers, painters. Don't be afraid to reach out. There's a weird syndrome we all have that keeps us from seeing our work objectively, and so it's very often we become stuck. Allowing another to step in adds fresh perspective, it also gives you breathing time to sort things out so that when you come back you can see both mistakes and triumphs without aide.
And since this is Saturday, I want to add a link that I've shared before, but it's too funny not to post again: Jack Handy's Deep Thoughts.
