My (imperfect, incomplete) solution to dealing with this is to establish a canonical format and data source. For example, my list of book to read is saved as an extensive Amazon Wish List. This both ensures I don't waste time reconstructing the hundreds of books I've already listed and lowers the barrier to actually obtaining the books (I could literally click once and have the book on my Kindle), leaving only the hard part of actually reading it. I'm still working on the mental process which transitions from the list to the action.
I spend a LOT of time on what I'll call "identity crafting". It's probably my most insidious procrastination tactic--far worse than, say, Facebook or Reddit.
What do I mean by "identity crafting"? Here are some examples:
In other words, "identity crafting" is some combination of making lists and daydreaming. And since the vast majority of the "identities" that I "craft" never become reality, I should really say that "identity crafting" is some combination of making lists and self-aggrandizing delusion.
What's so bad about this? Besides the obvious waste of time, this gives me a false sense of accomplishment and productivity--I often feel as though the "identity" that I "crafted" were already real, and I often feel as though I've already done enough for the day (week, month, year). Thus in the short term, this is a great way to ensure that I don't do any "actual work", and in the long term, this is a great way to become a poser with an epically inflated opinion of myself.
So... does anyone else do this?
