thinking about writing

I sit here thinking about writing goals. Should I sign up for the 2-year course? Should I find a local writers group? I do however, think I will join an online group "Sunday Scribblings" with a weekly writing prompt. http://sundayscribblings.blogspot.com/

What is it about the desire to write and the actual DOING the writing? There seems to be a large gap between the two, for me at least. Sadly, I THINK about writing far more than I actually write. I mean, aside from a few scratches here and there in a moleskine journal, working on a creative piece or project. The fact that I am not 'working' on anything creative, blocks me! Is that crazy? That's why I think I need some structure, whether involved in some group(s) or taking a class. It keeps the pen moving! Whatever works, right? I'm sure most writer's have their own battles with the page. If anyone has any suggestions, feel free to send 'em!
