There's a percentage - the number changes depending on who you ask - of books that, after purchase, never get read past the first chapter. I definitely believe that. Ive listened to audio programs that were on CDs in which the instructor announced a similar statistic.
Some people never seek and never find.
Some seek and don't find: bad advice, wrong circle of association.
Some seek and find and don't use: thinking the right way, acting the wrong way.
Some see and find and use: this group isn't guaranteed success, but all the success come from this group.
