I think people here might like Oliver Burkeman's books where he talks about this stuff a lot. I loved his book "Four Thousand Weeks", and there is a new follow-up "Meditation for Mortals" which I have not read yet but seems to be well-received.
He's one of the few people I've seen address what I think is the key difficulty with this sort of stuff: that you can think think that you're addressing procrastination/perfectionism when actually you are engaging in it (with a target of fixing your procrastination/perfectionism). It's a difficult situation to break out of, because it seems like any effort to break-out would necessarily have this sort of grasping, but I think he (and Buddhist meditation) talk a lot about that key challenge.
