1. Deep admiration and love for the young man.
2. Sadness and regret at the passing of time and the speaker's own aging.
3. Desperation to hold on to the beauty and perfection of the beloved and the moments they share.
In Sonnet 30, Shakespeare expresses emotions such as:
1. Intense emotions of love and desire for the young man, which he compares to a summer's day.
2. An acceptance of the transience of beauty and the inevitability of death, but also a determination to make the most of the time he has with the beloved.
3. Sadness and regret that he cannot prevent the passage of time and the fading of beauty, but also a sense of hope and comfort in the enduring power of love and poetry.
