Coping skills and adaptability are admirable qualities that help in these uneven times and can certainly guide us down the right path. These can be learned to a certain extent and should be strengthened as much as possible if we expect to be overcomers. I think the longest lasting success is found in something much simpler and more foundational: our identity.
If I am clear about who I am (son of the King, husband, father, friend, pastor) I won't allow these other events to pull me away from that. In fact, it's by reminding myself of the importance of who I am trying to become that helps me fight selfishness, anger, and stupidity. There's no guarantee I will always remember this, but hopefully I can see the value in maintaining the integrity of my character instead of responding flippantly to current circumstances. Don't let life's fluctuating events decide who you will be, but let your identity decide how you will respond.
