Resilience is about being able to cope and adapt to stressful situations. Some people seem inherently adept at "rolling with the punches" whilst others can really struggle in times of stress and change that are thrust upon them. Learning how to boost our resiliency equips us to better ride the inevitable waves of adversity that life throws at us.
Here are some characteristics of the resilient:
Knowing that "this too shall pass" and that a bad situation does not equal a bad life. Being able to anchor in on the temporary nature of the situation as a strategy to overcome it, that it will end, that it can be transcended. Perhaps life will never be the same again, but that believing that they do not have to remain in this experience long term and can create a new version of the future.
Releasing expectation that life rolls out in a straight line. Life rarely goes exactly according to plan for anyone; I don't know anyone who doesn't get some curly ones thrown at them through a course of a lifetime. Being able to accept that this is part of the human experience, and sometimes shit really does just happen - be that inadvertently created by our own hand, someone else's choices impacting on our lives or Mother Nature showing her force - that coping with the downs as well as the ups is an inevitable part of life.
Allowing themselves to feel their emotions. Bottling it up, denying what's happening is happening can lead to massive overwhelm in a crisis. So resiliency can mean allowing feeling what we feel. This can help us move through our feelings to a place of calm and acceptance with more speed. Tears have healing power. Having more compassion for ourselves in that it's okay to feel vulnerable from time to time doesn't mean we are weak or we have failed.
