I share what I can, but really it is up to you. You have to be willing to do the work so if you want to model seriously you have to have photos, there is no question about it. You can't wait for the agency to call and make your dreams come true, and you can't expect the agency to handle everything either. That is just not realistic, a model has to have a compcard, a headshot, and she is ready to go on castings...and auditions, and this can mean creating your own compcard, mailing it out, and being aggressive and smart about how you market yourself within your photos, and show on the compcard the photos best represent your best assets, .....you need marketing tools to get the agent, to get the job, to be a model, that is just how it is.
And you'know that isn't even enough because not one single person, not one single agency, not one single photographer, can make you a model either, it is up to you.
In this day and age not just one modeling agency will make your modeling goals come true. It doesn't just take having a modeling agency interested and making you a model, it comes down to you and your own ambition. But ambition isn't even enough because there are different levels of ambition, it is about what you are DOING with your ambition.
