I can't remember how I was initially introduced to Eric Barker's work, but now I find myself looking forward to his weekly blog post at "Barking Up the Wrong Tree". Barker's general approach is to provide a "How-to" for some challenging aspects of life. His posts are pretty thorough and research-backed (often from neuroscience).
I can't say that all his posts are a hit with me, but I've added many of his pointers to my own personal operating system. One of his short posts I really enjoyed was "2 Things that Lead to a Happy Life".
I hope you enjoy.
