Sometimes you're on the losing side. You're on the side that has less power, voice, money, time, or supporters.
When you're on the losing side, it makes you think a lot.
First, you think about the winning side and why they are winning. If you can get past losing, you truly have an opportunity to understand who you are and where you want to go. It could be that you actually honor the winning team and recognize that they have something that you want to work towards or on the other hand, you may realize that although they are winners, it's not who you are or want to be. In these cases, losing may actually be winning.
No matter, win or lose, what really matters are the choices and contribution you make and allies you align yourself to. We will often lose and sometimes win. Most of the time we'll be somewhere in between.
