There are many actors I know who have spent years worrying more about getting an agent than becoming a well-trained actor.
Agents are necessary, yes, but they do not make you or break you. As many actors will attest, simply having a powerful agent does not guarantee their success.

The happiest actors are the working actors. And just because you might not be getting paid for your acting, doesn’t mean that you can’t be a working actor. Every experience is experience. So, spend less time seeking out an agent and more time seeking out acting opportunities for yourself. From small plays to student films—you’ll be happily surprised how many seemingly insignificant opportunities are the ones that make your entire career. Besides, when the time is right, an agent will come and seek you out.
