I wanted to go to acting school, and I did a few modeling jobs to pay for acting school. I never aspired to be a model. I met lots of photographers, and I learned a lot about light - as a source of love and illumination, light as a gift of love. On film, that's a massive contribution.
You need to get in touch with your body ... do dance, movement, learn to be supple, or be someone who's coordinated, preferably. You have to study, train, and you don't have to go to school necessarily, you can teach yourself a lot of stuff.
I was never any good in the school theatrical productions. I always got a role like the March Hare.
