Whereas I am a terrible procrastinator, I often end up back the the deeper question of "Why am I doing this? Who am I trying to impress?"
I'm pretty sure I am just a far better planner than I am doer. And when I sit in a state of complete honesty, I'm actually pretty happy sitting in a state of not-doing. And just planning to do things, and living the experiences vicariously through research.
I procrastinate "good" things, too. In fact, sometimes I am guilty of procrastinating them more, as best I can tell because I enjoy the feeling of "looking forward TO" something. More than "having done" it.
I'm also a master of analysis paralysis!
I think I do the same, enjoy the experience while planning a fun thing, and not necessarily needing the experience of really living that plan. Though what often ends up happening, eventually, is that I go through with a plan that I had already thought out long time ago. So the execution comes seemingly abruptly to others, but was actually a well thought out plan.
