Some people are like sponges. They can soak up the work / pressure, take it all in, and then deal with it. These people make good managers.
Some people are like hard dry chipboard. They don’t soak up pressure very well they end up just spraying it all over the place. A deep puddle becomes a shallow pond ⇰ which in turn becomes a kids swimming pool ⇰ eventually an infilled lake. These people end up throwing tantrums and loosing their cool over pointless insignificancies associated with heightened stress levels and anxiety all caused by the inability to juggle more than one thing at a time.
Relax and enjoy the few moments you live, for it is surely not worth all the hassle and stress.
