How does one write a sonnet?

How does one write a sonnet I wonder?

I imagine it as a daunting task

My pride is quite sure to fall asunder

And well, frankly I am afraid to ask

What is an iambic pentameter?

Such a strange thing it really seems to me

It well and truly is a brain beater

And yet other poets write easily!

I hear it also needs a common theme

But that could well be very hard to do

I guess this shall remain a fever dream

It seems the only outcome is to lose

Why do I bother? I question a lot

Really the drivel I write is such rot
