Job status: Not offered to me

I spent some time recently exploring another job. I was one of the final candidates for the position, and while I am not entirely certain that I wanted the job or that it was in line with what I want to do next, I REALLY wanted to be able to make that choice on my own.

I guess I just assumed I would be offered the position - mentally I was already there. Now, I have to get back into my current role and find some motivation. Where oh where is my motivation?
