love this. my father had life goal to write a book that would still be read 20 year after he wrote it. He did that. This, my first book, i wrote to be still valid after 5 years (i have low goals, lol); and it's now at 25. My agile book i wrote to be still valid after 20 yrs, and happily, it still is :) So I celebrate every time one of these posts pops up :)
