So, I haven't posted in a while — This Fact or Fiction seemed to fit pretty well, if I say so myself.
Seriously though, it's always better to have something over nothing. And, showing up late versus not showing up at all shows you care, even if it's just a little. Turning in work late, sure not the best thing, but the act of doing it at some point, is better than not at all. And, sure, certain things lose their luster if the "right time" has passed by, but there's got to be something (anything!) said for trying at all.
Time tables matter, but only to a degree. The notion of a right time and place for something often does nothing but stifle whoever is involved. So, do what fits and do it in your time. Screw metronomes and alarm clocks, watches and schedules. We all have to answer to something or someone at the end of the day, and honestly, it's just ourselves. Do what you want, is what I'm saying.
