Study acting at a university or an arts academy. Though it's possible to act without a formal education, if you don't live in LA or New York, this is a pretty standard go-to option. You'll get exposure to the pros, learn about techniques, and get automatic chances to work on a stage. This will also help you build your resume, get exposure, and set up a network of colleagues and contacts. Your teachers will constantly be pushing you to do more, practically taking care of the motivation part for you.
