Deadline == Commitmentfleeting
I often see people writing deadline on top of task “because it is important” and, when the deadline is past due, just put another deadline.
I think this is not being intellectually honest and lying to oneself to have the illusion of control.
As far as I am concerned, I decided to believe that a deadline is a commitment and that, because of that, I will do all in my power to fulfil the deadline. Reciprocally, I will renegotiate the deadline as soon as I believe it is not doable. you are committed or not, but never in between.
