Just read this mind blowing book, called Radical Honesty and managed to extract 62 lessons from it, although I believe you could find at least 200. It sheds a perspective on honesty and how important it is in order for you to succeed in any aspect of your life, but primarily to succeed in conquering your own mind and the so called jail you live in. I would call it a box (less dramatic and it goes well with my life philosophy) that you live in.
Whatever it is, the book is worth reading. Check out the lessons here:
