It’s usually because of lack of sufficient reason to be doing the thing or lack of a sense of control in the initial engagement–physically, mentally, or emotionally. If the life of someone dear to you was dependent on you finishing the writing project in the next 24 hours (an outcome meaningful enough, I would guess), we think you’d find yourself breaking through some resistances to getting started. Or, if you absolutely knew what the first four paragraphs were (control), you’d find it easy to get started.

Maybe there’s a good reason not to choose. There is probably a fine line between “intuitive holding,” though, and procrastination or resistance to making decisions. But before you think you need to do something about this, you might ask yourself which it is.
