I have believed throughout my modeling pursuits that if I wasn't in a magazine this month, or doing what I wanted..it was because of my own effort.
It takes a huge amount of try to be a model.
To make the phone ring it does take work, and modeling is what you make it.
Staying ambitious is key. Knowing how to market yourself as a model. Wanting to try, and wanting to do the work, knowing it will be a challenge and accepting that but still fighting for opportunities along the way. The "want factor" is a hug part of doing anything you want in life.
