I read the article and the books. While I have never been able to fully implement it, there is something in radical honesty that rings very true to me. I now realize it is about Blanton's diagnosis: lying will rotten your life, by forcing you to create a self that is far from your true being. Nothing new here, Di Mello and Tolle have modernly approached the same subject from different angles, while it has been covered in many philosophical and spiritual texts throughout history.
But Blanton proposes a kind of shock therapy that, while possibly effective, is extremely difficult to put into daily practice. In short, by always telling the truth you will eventually build a fulfilling life, but you will have to go through a lot of drama and resentment, possibly pushing a lot of people away from you during the process.
Is it possible to do it in a better way? I really don't know, but I have tried a lot of things in the last couple of years that seems to be working. It basically involves trying to build a lifestyle where I just don't need to lie anymore. Start-ups are great for that compared to other work environments, but so is moving to smaller communities, being completely open and honest with family and friends, etc.
Whenever I put myself in a position where people's opinions can significantly impact my (perceived?) well-being, I find it very hard to be totally honest and close to my true self.
