Just because you can't have nice things, doesn't mean you should have to justify not having them. Here are some efficiency justifications:
Why waste time on punctuality when you can just wing it? Who needs to be early when you can be fashionably late? Justification #2: "I'm not actually doing anything, I'm just reorganizing my to-do list."
Why bother with a to-do list when you can just stare at it for hours? The act of rearranging tasks is, in itself, productive, don't you think? Justification #3: "I'm not actually working, I'm just contemplating the meaning of life."
Who needs productivity when you can spend your time pondering the existential implications of it all? It's all about perspective, folks! Justification #4: "I'm not lazy, I'm just conserving energy for more important things... like binge-watching Netflix."
