Does anybody model or know models? How can I get more opportunities to model?

Sadly I have been rejected because I'm not tall enough to model. I have had some experience modelling I take anything and apply for everything. I workout and have a good diet to stay fit. But still I am always never called back and when I do get called back my pictures never make the cut.
