Like many of the sonnets, Sonnet 29 is actually a single sentence. In the long introductory clause, what does the speaker say he envies?

The speaker finds himself envying what others have, and in lines 5-9 he sees almost everyone as having something he lacks. He wishes to be like "one more rich in hope," perhaps meaning hopeful or literally wealthy; "featured like him," refers to someone who is handsome, with beautiful features; and another is "with friends possessed," or popular, unlike the poet (as has been established in the first two lines). In line 7, he envies the artistic talent of one man, and the opportunities afforded someone else.
