Sonnets about Sonnets

William Wordsworth seems to be saying that sonnets are restricting, and yet, he chooses to write in sonnet form because he must; it is in him to write sonnets, "In truth the prison, unto which we doom/Ourselves, no prison is: and hence for me,/In sundry moods, 'twas pastime to be bound/Within the sonnet's scanty plot of ground". I hear Wordsworth saying the so-called prison of sonnets, or of nunnery, or of being a maid, is not in actuality a prison. Perhaps you are doomed to be locked in by a certain fate (job, lifestyle, writing technique) but it is that fate that makes you who you are.
It was his time to be "bound" by sonnets and he doesn't regret that, just as the nun is happy in her narrow convent room- it was her choice and is her life, should she choose to spend it in way others might not is irrelevant to her happiness. Who cares if people decide not to be nuns? They shouldn't if they don't want to, but their choices and her choices are separate.
The hermit is happy alone in his home. Perhaps I would not find it a fulfilling life, but that's why I didn't choose it, he did.
I hear Wordsworth appreciating the confinements of sonnets. It's like he wanted a challenge, to have his writing narrowed into beats and lines, "Pleased if some souls (for such there needs must be)/Who have felt the weight of too much liberty,/Should find brief solace there, as I have found." I feel Wordsworth saying there need to be sonnet writers, nuns, hermits, students, maids, weavers, bees...because each to his own. He man finds his own happiness right? And however brief the happiness, however long the still eye of the storm lasts, it is a pause from that which we cannot bear. Sonnets allow Wordsworth to have some outlet of creativity that he didn't have with normal poetry. I hear Wordsworth hoping others can find the same joy in sonnet writing as he has.
