Long ago, after a life event, I decided to ban stress as an "illogical activity".
I've got so good at it, that sometimes I have to feign being stressed so the higher ups don't think I don't give a damn. (I do, I just don't consider work "life or death")
As an example: Something that used to drive me bats was being asked to do something I clearly knew was wrong for the project/company. Before, I would fight hard to make my point. Now, I try to illustrate my point the best I can, then I just do as told. (I bill by the hour anyways)
On a previous project I actually told a non-technical owner: "What you are asking me to do is basically to hit your finger with a hammer.. That said, it is YOUR finger and YOUR hammer.. so say so and I will do" (it actually worked!)
