I'm an agent for technical people; I'm their advocate, guiding them through contracts bureaucracy.
Learning / Being Challenged
Day to Day
Every day is different, but it's a balance between document preparation, research on various space technologies, and mitigating client expectations. It's a lot of balancing several projects in various states of completion at one time, so essentially we're talking about project management. Something that I take upon myself to do (because I'm Type-A sometimes) is constantly think about how I can make my job easier and also save taxpayers money at the same time.
Advice for Getting Started
Here's the first step for everyone
Do something. Do anything. In my experience, where you are doesn't matter as much as what you do with it. My cashiering experience at Wahoo's Fish Tacos at UCI directly led to my next job, which led to my next job, which led to my next job, and so on. None of those experiences were unimportant, even though the jobs weren't really related to one another. Treating the job like an opportunity and building something within it--even something small--can go a long way.
