No matter who your agent is you should always look out for your own dreams and fight for what you want. Modeling to me isn't a joke or a fluffy word, I take it seriously and I earn all I get with research and by being smart about it and realistic about my pursuits.
It involves mailing photos over and again a few times to get work. It involves resarch and being honest with myself. There are certain modeling jobs I won't ever get, like walking the runway. But I really don't want to do that anyways. I want to do print work and for that, I have learned, I don't have to be a certain height, I just need quality photos and I need to work with an agency that works with models of all heights. And I have and I do. I don't waste time.
I am not tall, but that doens't mean I can't model. I just find ways to use what I got and get ahead!
