I'm confused. What really is the work of a true marketing assistant?

I used to think that I am not really performing to the best of what I am capable of doing. You know, I've been a marketing assistant of central books for 6 months already and I seem to be ignorant with the real-time concept of the field of marketing. Or am I really in the field of marketing? Take for example my recent job as a jack-of-all-trades multi-tasking highly skilled sales/administration employee in Glorietta and main branch in Quezon City. My job description is totally fully general in its sense that I often end up idle in a spot waiting for customers in Glorietta or trying to search for anything to do in Quezon City (just to tell the hidden cameras that I am such a hard working freak). I do act as a sales staff and converse a bit to tell tales to customers about how our books are clearly printed and perfectly binded aside from flooding them with different sets of brochures and offers. I do also computer reports and other typing jobs since (sad to say) my co-employees had limited knowledge for such technology. Alright. Marketing might also mean handling sales and doing the verbal flowering conversation with different sorts of people, but where can I go aside from that? I thought of a marketing assistant as formulating strategies and working with a team of marketers to boost sales and increase the image of the company. BUT and another BUT I know that what I wanted to happen is not applicable in my company. Why? It is simply because there ARE only 2 marketing employees existing and it is me and my boss.

Yup.

So you might as well digest my point. Is being a jack-of-all trades person equates to being a marketing assistant?

Maybe I am not supposed to be called as a marketing assistant but a mere assistant of the assistant. It is just that I am called as a marketing assistant for the sense that I am under the marketing manager which I do assists giving leaflets to law schools, marketing our publish on demand, editing marketing articles and manning book fairs and exhibits.

Wait.

Let me think.

Ok.

I cannot think for more. It's just that I want to be a script writer instead.
