In the past I've made that mistake a lot. I worried about things I shouldn't have, I have harmed my health because of a job and been through quite toxic work environments where people just constantly whine and complain about every little thing when it was absolutely unnecessary, but those things spread unfortunately and poison even the most optimistic people if they are not careful enough.

People would be better off if they realized that certain things are simply unnecessary waste of energy when it comes to jobs.
