Perspective

I might think the word you are referring to is perspective. I first came up with Illusion, then Mindset, but Perspective slipped through my mind as well. Because, no matter how you take a look at life, there is always someone with a different perspective on the same things. Some things might not seem to be what they are to you and the other, but most things are identified with emotion and own true intentions/believes. Emotion from situations you have experienced in the past. Emotions you can or can't relate to. And that is only because of how and why you take a look at things.

Seeing the corruption in the photographs, made me guess the word was an illusion. Seeing the guitar box and the homeless guy made me think it was the mindset. Checking out the picture with all the different doors and the last picture as well, made me think you have a choice. Well, of course, you have a choice, but a choice can only be given by yourself and if you decide to take it or not, and that depends on how you take a look at things and see things in your own perspective.

No matter where you look, it will always be the same. The only thing you can hope for is change.

The truth lies in the eyes of the beholder. Everyone holds their own truth, everybody is right, nor wrong unless they agree with being wrong. But all of these images resemble hope to make the world a better place in their own way.

The word is Faith or Hope.
