I'm not an expert on (always notice that any sentence beginning with this is going to wax fake expertise later) leadership but i firmly believe that it's an evolving process. There's no set template for leadership. What worked for leaders at IBM might not work for those at Google. One can take as many notes or make as many bookmarks as possible but the fact remains that leadership is an intercourse with a given situation. It differs from personality to personality. In a society where leaders are few and followers way too many, that's an interesting conjecture. Don't you think so? If no, you should ask yourself whether you're a leader. If the answer to that question is yes, you should ask yourself whether you've created your clone or are in the process of creating one at least. If the answer to that question is no, then you basically lied. You are not a leader yet because a leader's most primal job is to create his replacement. Of course, that doesn't happen overnight. It's a painfully slow but fruitful process. The idea behind this preparation is to ensure that the followers (or an organization) doesn't suffer if the leader (which you claimed to be) dies in a freak accident tomorrow. Grooming is seriously underrated because of the clinginess attached to it but it's a necessary move for the future. If Messi moved on to another club next season, Barcelona won't suffer immensely because there's Neymar. Messi's grooming of the young Brazilian is public knowledge. Just like Ronaldinho's grooming of Messi is.
