Ohhh Tony don't you see the irony in your mindless rant??? In a single rant you simultaneously imply people need to willfully execute their choices ("Sort your priorities out!") as well as attempting to shame them for willfully executing their own choices ("You've booked time off work for HoW, are you serious?"). I remember what it's like to be a young idiot myself, and the good news is you will likely grow out of this phase. Until then however, take your own advice and worry about your own priorities, not others'.
