1. I cannot be an actor.
2. I am not an actor at all.
3. I cannot become an actor.
(What does #1 mean? Is #1 similar to #2 or #3?)
1 and 3 are the same. Those sentences are referring to "becoming" which is a future possibility.
2 is different. It's referring to the present, what the person is or is not.
