Hi Anastasia — I don’t preserve them beyond my notebooks. I’ve had plans to go back through my notebooks and digitize the highlights but it’s not a priority. If thoughts or experiences repeat themselves then it’s something I pay attention to. It’s a sign that I might need to examine it further. For journal entries that are more transient I don’t pay attention. And of course I blog about the most pressing entries. That’s another way of preserving what’s most important.
