Breaking Through The Block That Hinders

The more I try to plan out my latest story, the more questions I seem to come up with. More and more back story seems to arise, endless questions and 'rules' of this world I'm creating that I seem to be losing my way.

I guess it's because I've been out of practice for so long that each step in the process of crafting this story feels daunting. I've put so much pressure on myself now that I'm afraid of making mistakes.

I know in my mind that not every work on the page has to be perfect. But I'm growing impatient, I want it right…NOW.

I wonder if other writers find it this difficult. Does every moment spent NOT writing feel like a moment wasted? Every demand for your time on something other than writing make you feel more desperate, more determined, more hostile? The only good I can find in this is that my passion has returned, and is more intense than I've ever known.
