Have a true purpose outside of this sc-mmy place. It will give you peace of mind and keep you going on what truly matters. To focus your energy on the mess that is MetLife, in the hopes that some day, the management and the culture will get better, is a losing battle and robs you of joy. MetLife is not a high performance organization and never will be under the current leadership. It's not worth their attempt at psychological warfare impacting your mental health.
