Ideas rot if you don't do something with them. I used to try to hoard them, but they rotted. Now I just blog them or tell people about them. Sometimes they still rot, but sometimes someone finds them useful in one way or another"
This is one of the deep principles of my life. Expressed very well.
Ideas need to be exorcised or they continue to haunt you. If you can't get them out, you can't leave them and move on to something else. That's why I found the artificial barriers of the AcademiaVsNewMedia/GranularityOfScholarlyWriting so difficult. In moving between the idea and the correct expression I'd get lost. It's why I prefer UnfinishedProjects.
