The magic about studying research like that found in How the mighty fall is that it shows us not only how to recognize where we are but what steps we need to take to keep ourselves from failing.  It takes a realization and acceptance of where you are and what got you there.  It takes the perseverance to never give up, to never give in, but to always be willing to evolve your position.  It takes a willingness to question your direction and carefully consider the questions of others.  Most importantly it takes a commitment to recognizing not only when you’re on the wrong path but when to get off it.
