I'm not always late, but I often am. Normally when I start a new job or commitment I'll feel a little on edge at first, so I'll make the effort to arrive on time or slightly early. As time goes on I start caring less and sometimes even feel resentful, so I'll slip more and more. The problem is worse in the mornings because I don't sleep until after midnight. I know in my head I should go to bed early, but I honestly feel more alive late at night? Also, consequences don't feel "real" to me until they're right in my face.
