My second blog post was on the The Value of Mistakes: Mistakes and Learning. Today there is a post linked from HN, Make a Mess, Clean It Up!, that showed me a point I missed.
Making mistakes on purpose so you can learn from them. One advantage of doing it on purpose is that you can choose your time, so you are fresh and ready to learn, but even more importantly so you can do your learning under controlled circumstances, where you are not going to irritate and inconvenience, or worse, anyone else.
The general idea of making mistakes on purpose I vaguely remember from old Whole Earth Catalogs (I think it was in them, or maybe a theme I took away from them). I should have remembered it when I wrote my earlier post.
