This book which is based on incredibly suspicious evolutionary theory is simplistic and outlandish. The authors make a big deal out of saying that we have two forces warring against each other with one side wanting short-term pleasure and the other wanting long-term benefits. Well, duh! We all already know that. This warring is supposed to occur because we have not completely evolved out of our "primitve guidance systems" (PGS for short)! Their solution to this evolutionary flaw is even worse -- create enrironments of critical situations that force you to act. Haven't we all been trying to bully ourselves into doing what we need to do for long enough? These authors now want us to invite others to do it for us!I would highly recommend a book called The Now Habit by Neal Fiore if you really want to know why you procrastinate. Read that book first and I'm sure you'll agree it's the only one you'll need.
