Concourses

There are three options, but I must take one,
And question if the other two exist;
I can but know what I've already done,
Nor can I tell what I, perhaps, have missed.
Perhaps they are the same, or but a twist
On that same formula I know I know;
But it is possible that they are kissed
By better sunshine or a deeper snow.
I cannot truly tell until I go
Where I have never gone, and so pursue
Chimeras in the mist - and I say no.
I'm happy here, and so I choose to do
What I am doing, what I've done before
From deep content, not from the fear of more.
