What are the steps in becoming an actor?

There are no particular single set of steps of becoming an actor. Everyone who becomes an actor does it just a little differently from everyone else. It is going to vary from person to person. I recommend that someone wanting to become an actor when they are an adult, begin by being in all the school and community plays they can. This is also the best advice for someone wanting to become an actor while they are still a minor. Then when your participation in these plays indicates that you have the extraordinary talent needed for professional acting, you should take some well selected professional acting classes. When you are a sophomore in high school it is time them to start thinking about how to proceed, whether to go right after it, or whether to go to acting conservatory or whether to go to college. What you have done up to that point will help you make that choice. My free e book, The Tao of Acting, comes as close to any to setting up a workable plan to become a professional actor. Given you have the talent and personality and know how and luck of course, the Appendix on Tao and Having a Career in Acting may work for you.
