I think he says it better...

I made a big decision a little while ago.
I don't remember what it was, which probably goes to show
That sometimes a simple choice can prove to be essential,
Even when at times it seems to be inconsequential.

I must have been distracted when I left my place because
Left or right, which way I went (I wonder which it was!)--
Anyway, I chose my path, set forth in that direction,
Utterly absorbed, it seems, in quiet introspection.

For no reason I can think of, I just led myself astray.
And that is how I came to where I find myself today.
