One of the tough things about being an aspiring writer is the "aspiring" part. You have to write so that you have samples to show people, but no one is going to pay you to write those samples, so you have to also have a full-time job so you can pay rent and eat. That means all your writing happens when you're not at work. So does your sleeping. And your dating. And your TV watching. And your working out. (Maybe I should stop blogging so much, but the questions have been piling up - I'll get to them all soon, I promise.) I'm trying to get back on the fitness bandwagon (I despise having a cliche New Years' resolution, but when I'm jacked I'll be able to beat people up for calling me out on it)...and that doesn't leave much writing time. It seems that you're either a fit non-writer or a fat writer.
One of the tough things about being an assistant is bladder control. For much of the work day, I have to pee. This is my dilemma. No, it's not like we don't have a bathroom nearby, or that agencies forbid peeing like factories in the 20s...but you just KNOW that the moment you step away, the messenger you sent is going to be held up by the Universal Gate Gestapo, the mailroom will lose two $800,000 checks, clients will call and get voicemail some shiny CAA agent will use their distress to sweep in and poach them, and after your boss gets an email that someone wants him to join something called Facebook he'll start intercomming you AMANDAAAAA? AMANDAAAAA? HELPPPP! for the whole department to hear. So sometimes it's really just better to hold it.
