I haven't really decided what direction I want to move in yet but, as you say, my foot is in the door and it's not the worst position to be in. As for tea, I already do that too at no extra cost, I swear my brewing talents are being wasted here! Good thing about being a runner is that you tend to do a bit of everything so I've worked with camera crews before, seen some of the editing in process and stuff so it's all good experience for when I do make a decision. I even get to meet the occasional D-grade celebrity!
Yeah, it's not ideal and it can often be stressful but I don't hate it! Everyone above you wants you for themself so the best thing to do is decide who the most important people are and make them your priority. It's impossible to please everyone so ignore the whiny middle people and pander to the producers!
