It means that James Franco enjoys doing his job. He doesn’t get stressed or annoyed by his job like he would if he was doing something else. Since he is happy and content with his job, he doesn’t feel the need to take a vacation to get away from his job.

subjunctive mood
The verb were should be bolded in this sentence. It is written in the subjunctive mood because it gives a statement that is contrary to fact. The speaker says IF I were a teacher, which shows that the speaker is not actually a teacher. The second half of the sentence is written in the conditional mood, because it is based on the condition of the speaker being a teacher. Imperative mood verbs are used in commands. Indicative verbs are used in statements of fact. Interrogative mood verbs are used in questions.
