is the vague pronoun in the sentence...
True! By using standard speech, the majority of your audience would be able to understand it.
The one ingredient that helps, but is not necessary to an effective speech delivery, is that it is the result of the speaker's natural talent and gift.
With proper preparation and a healthy dose of courage, anyone can be an effective public speaker. The important elements are that message delivery is impactful, the speech is influential towards the audience, and that audience expectations are met or exceeded. Natural talent helps, but thorough preparation and careful speech planning go much farther towards an effective speech.
This is definitely true, I would focus on how hasty romeo is.
The main point is where he sees Juliet at the party and says 'did my heart love till now?'. This comes right after his long petarchan soliloquy which focuses on his mourning over losing Rosaline.
He spends a whole scene moping over her, but the moment he sees Juliet he has forgotten all about her. This is just one example of his fickle tenancies, and makes the reader question whether he ever loved or was it all just lust?
Another example is that in the first scene he discusses his hatred for violence, yet after mercutios death he murders tybalt without haste. Romeo becomes increasingly fickle and unpredictable as the play progresses.
