Whether you can model or not, well it doesn't come down to someone thinking you can, the first step is you thinking you can. The second step is you knowing what you CAN model and understanding the way marketing plays into the modeling industry.
Think about what makes you marketable? what makes you sellable? Why would a brand want to hire you as their model? Why would an agency want to work with you?
It isn't about a confidence builder it is about marketing and business.
Being a model isn't about height. It is about showing up, wanting to do it, and for new models it is about doing the work to create a compcard, getting envelopes, mailing it out, and trying.
