If you must begin somewhere, this will do.

The If is telling. Already questioning your own premises, or, worse, purposes. 

The You vacillates. Like a fish in a stream splaying prisms. Prisming prisms? The second-person refracted in prisms (to stick with the theme): allowing you to speak of and of you. (You again).

Must. Is this a tense? A modal? What does it convey? Oughts and shoulds are trappings. We’ve barely risen past If and You: don’t add more complications. (What would life be if must was the only tense we thought in?)

Begin

This is Somewhere, possibly. Or nowhere. Or anywhere. I am here (see: You, above). in the woods. The sky is gray and the light spills from behind me blazing the cedar boughs green. To this, the young maple leafs shake their appreciation like approving fans. The cat curls beside my feet, churring and cleaning and settling into the sun patches lightening the blue rug beneath. 

Will do: meaning: suffice. Function. Latin sufficere “to provide, appoint, have enough strength or capacity, be adequate.” Already the stakes have been raised.
