Hey, "The friend is me" guy here.  I never really thought about it in those terms, as far as which thing terrifies me less.  Thinking back, I would definitely say that doing shorter things is much less terrifying, and also I can actually DO it in the first place.  Longer things sap energy directly out of my soul when I try to do them, and that makes me wonder if I'm doing it wrong.

The problem I'm currently having is that while I can make as many short things as I want, they all contain extremely personal info and I do not feel comfortable showing them to most people.  I've tried to transition to something that doesn't feel as awkward to share, but I'm afraid that along the way it will all fall apart and I will be buried by the resultant avalanche of crippling self-doubt.  My inability to get all this to "click" together is driving me insane.  How do I avoid going insane in this way?  (sorry for this super-long question btw)
these sound like the thoughts of someone who knows they are supposed to make it. the great news is, you will probably not be able to focus on anything else until you make it. you will spend every day trying to find ways to get this together. there is no escaping the fact that you are going to get it together. just remember that any way is the right way. you should see some of the dumb things i tried when i first started. oh wait, you can because i posted them all online
