I like the message in the post, but some of the examples seem far-fetched.
Dan lost four or five hundred thousand dollars..."or something like that." Maybe his capital base was in the millions, because otherwise he might have wanted to pay a little bit of attention to money management.
Then it says "Dan knew how to lose". Got that right.
And what about the next guy, went full-time and lost 70% of what he had made in the previous five months in just
four days!

Someone buy him a copy of Van Tharp - please! Or at least advise him on how to place a stop.
I do like Bill Lipschutz description of "insanely focused" though.
