Somebody asked him to take on something worthwhile that would have helped people outside his own family, and he thought about it across a holiday weekend and said no, because he did not want to do it. The post about that is uncomfortable and honest, and it argues that loyalty pointed in every direction at once amounts to loyalty to nobody.
Two further posts treat goal setting as something capable of going badly wrong, including one claiming it nearly killed him, which is a position almost nobody in this business takes.
The practical writing covers advertising on one platform, and gets specific to the point of bluntness about which images perform, while being equally blunt that nobody quite knows why they do.
Another post asks readers to stop taking it personally when somebody declines to join their company, and points out how the atmosphere changes when you next approach the same person yourself.
Ten posts. Read the loyalty one first.
