Aside from what tsar said, you could volunteer at several community theatres to learn about what's required and develop the skills you will need.
I volunteered at several local theatres in North and West Vancouver for a few years - I did scene set changes, painting, prop collection, ushering, serving, etc. Others did electrical, set construction, repairs, and other related physical things.
You have to commit and follow through, because they're depending on you, but they're a great way to learn and you may meet people who can help you in your endeavours.
Volunteering is a bonus for everyone.
