You do have talent. It just might not be in acting. If you love theatre, there are many skills and needs for a production outside of acting. Lighting, Sound, Costumes (can you sew? Theatre troupes are always desperate for costume builders.), Scenic Artists, Electricians, Carpenters, Painters, Box Office Personel, Graphic Artists (For programs, advertising, etc.), Administrators, Stage Managers, Running Crew (Stagehands who move things, pull curtains, hand props to actors, etc.), Make Up Artists, Directors, Drivers, Runners, Gofers, P.R. specialists, Photographers, etc, etc, etc.
Every theatre troupe needs these people to help with a successful production. If you like the people in theatre, offer your services to the local community theatre. They will be very glad to have your help. In many theatres, the behind the scenes peoplpe get more respect from the actors because they know you make it possible for them to be able to perform. I know, I’ve done almost all of the above except make-up.
I also started at the community theatre level. Now, I am a professor of theatre arts and a respected professional in the Houston area. I get so many requests for my services I can not accept them all.
And the parties are the best! I still remember one that the second time the police came to quiet us down, the first group of police were still there!
