Volunteer at a local theater company. Local community theatres are always looking for volunteers to help with props, sets, costumes, etc. Being a volunteer will allow you to study actors in rehearsal, will help get you familiar with the acting world, and will introduce you to people in the industry. Next time the company holds auditions, do a monologue! You already know everyone in the room, so it's the perfect place to start auditioning. They'll most likely give you some good feedback as well.
