Losing faith in yourself

(This is the sixth Stumbling into Publishing post.) It always starts well because I always start alone. Working by myself, I have the peace of mind to just focus on the work, work on the components, polish the details, and simply go where my interest takes me. Sometimes you share with people you trust; never more than with a small group. Sometimes you lose interest and just stop. You are working alone and so who is going to judge you for giving up?
