Success in a dynamic world requires mastering what might be called “the discipline of productive destruction.” That is to say, the willingness to destroy yesterday’s strategy to build tomorrow’s success. This doesn’t mean abandoning your purpose or betraying your commitment. It means committing to the outcome enough to abandon any particular path that no longer leads there. For the 50+ crowd, this applies directly to reinvention. If the ground beneath your feet has changed and the path is no longer the same, pivot.
