Does Our Street Photography Have Meaning?

I have been practising Street Photography for some time now. As the years have gone by I have been happy with the progress that I have made, both aesthetically and in obtaining knowledge. A few days ago I was reviewing my portfolio, trying to understand exactly what direction I want to go with my body of work. As I went through the images something started to bug me. In a wake-up call style moment I found myself in front of my laptop asking - "Does my work have any meaning?".
