Without knowing your age it is hard to give you advice. The few people I know who've tried getting into acting did the following:
1. Tried out for and were in dozens of plays and musicals from the time they were very young all the way through school. They were in summer theater program and local community productions. They got hired to be in local music videos, ads, and student productions. They didn't wait for a big break or some magical invitation -- they worked on their craft in any way they could and built a resume of work in the process.
2. They went to school. In addition to acting they went to college for acting. Some with to community colleges, so as full-time university students, and some at private acting studios and with coaches while they worked.
3. None of them were above working a "day job" to support themselves while they auditioned.
4. In all honesty, most of them ended up moving to either LA or New York or other major cities. Once they'd reached the point where they really wanted to audition for paying roles in TV, Movies, and theater and or try their hand at improv, then needed to be where those jobs are plentiful.
5. They got headshots, put together audition tapes, and hired an agent
