Preparing

It may take years of practice to develop the skills needed to be successful as an actor, and actors never truly finish training, much like athletes.  They work to improve their acting skills throughout their career. Many actors continue to train through workshops, rehearsals, or mentoring by a drama coach. Every role is different, and an actor may need to learn something new for each one. For example, a role may require learning how to sing or dance to a certain extent. Or, learn about a different era in time. These take dedication and NOT just a passing interest, or having read a couple of articles on the subject.  I can promise you when you actually go to the audition, perhaps the one that could change your life and lifestyle, that there are going to be those with a little more 'focus' and 'preparation' than a passing interest that show up as well. Many aspiring actors begin by participating in school plays or local theater productions. In television and film, actors usually start out in smaller roles or independent movies and work their way up to bigger productions. BUT THEY DO SO WITHOUT LISTENING TO A BUNCH OF ''NO RESUME' ACTORS DISHING OUT ADVICE.  Be sure this avenue is right for you and then go about doing something about it.
