The blogger at 17 Mile is shutting down his blog due to, among other things, the collapse of his strategy. His last post is a very candid assessment of his performance, strategy and current abilities. I found the post-mortem, along with a review of his prior investment theses (mostly well known names), helpful in reminding me about my own limitations as an individual investor, concentration/diversification, and what types of investments I should be considering versus putting in the too-hard/too-levered pile.
In case anyone else find's it useful, here's a link: http://seventeenmile.com/
