Always front

I took this picture at the corridor of the building I live in, where I grew up. It reminds me clearly of a dream I had after, where I walked through so many places to reach something I dunno. One of the places was this corridor, filled with a deep fog. I see this photograph as a sign that I have to keep going despite the troubles, despite anything that gets me down and thinking about give up. It might have other meanings to different people, just tell me yours.
