16. Getting Drunk On A Weekday Just Isn't Happening Any More

Not because of the hangovers, but because you have so much to do now the next day that feeling crappy from wine on a Wednesday just isn't an option for you. Going to bed at 2am after dancing at a student nightclub might seem like a good idea in trying to relive being that age. But realistically the consequences will involve you having to wake up at 6am, to catch a train to London, to consider vomiting on the Tube, to sitting at your desk all day dreaming of your bed, to achieving nothing all day, to swearing you'll never drink on a school night again. 25 year olds: it just ain't happening anymore. Leave it for the weekends.
