As for procrastinating, that is NORMAL, but exacerbated if you have an extreme interest. The interest almost always wins out. That is one reason I almost never did my homework.
As for indecision, I never really thought about that. Maybe it is for the same reason I usually order the same thing everywhere I go, and have a favorite backup choice for certain genres, and hate change. I try to anticipate problems, and pick the best choice. Sometimes, that is just TOO difficult.
