One of the interesting aspects of leading is success and how one deals with it and learns from it. To paraphrase Lao Tzu, one celebrates victory in war like a funeral, because there are winners, yes, but there are losers. In war, of course, this implies celebrating victory is the manifestation of delight in killing, but it goes deeper than that. The leader understands that for them to succeed, it sometimes means that someone else did not.
Celebration sometimes is more about ego and less about joy for one’s accomplishments. Therefore, we have to be careful that celebration is genuinely about that joy and not rubbing salt in the wounds of others.
This kindness may seem antithetical to some, but the goal of a true leader is to even bring the vanquished into the celebration and create a win for all.
