If you can act with feeling you are on the right track.  If you can act and make the audience feel something then you are an actor.  Good actors can act so that the audience is feeling the same emotions that the screen writer intended.  If you just learn the lines and don’t have the ability to convey emotion then give it up.  I think that acting is a inherited trait, not something you can learn.  Eric Gonchar is one of those actors that were born to act.  If you want to be a good actor then I would give it a try.  Don’t be disappointed if you fail.  Most do.
