Why does one experience so much akrasia in trying to revisit past insights? Maybe it’s something only I experience, but I doubt it.
When reading I try to mark, comment, flag, etc. deep/interesting insights. While consuming them my brain is releasing quite a bit of positive feedback, and its enjoyable just from that standpoint.
Why is it then so hard to pick up an old book and look at the 3 pages out of 500 that I have marked as truly insightful? Yes it is possible that a lot of the information has already been internalized and incorporated into myself. And yes I will likely remember the insight upon rereading and it will not be quite as enjoyable. Yet on average, per unit of time spent, I am likely to experience far more pleasure, insight, etc. from reviewing past finds than plowing through new, unrefined, ore.
