Castles in the Sand

I don't know about you guys, but sometimes the way I "plan" "vision" or "think about" life feels exactly like this picture. A large, complicated, amazing, interesting structure built on sand, with sand, not really liveable, not at all practical, mostly make believe, and only ever real in a "virtual" sense. Not even really "my own".

This photoshopped image uses a variety of other images, other ideas, other realities, other experiences - which are then carefully spliced together to create something that "looks" real. The person who created this image did NOT go to that beach, gather all that sand together, and actually MAKE that castle. They didn't even go outside when they made it. And I'll be that they made it using photographs that THEY didn't even take. Someone else probably took the picture of the ocean and the sky, and just as someone else probably created that sand castle, someone else also took the picture of it.

And I'm wondering just how much of what's in my head is ACTUALLY mine? And why are my hopes and dreams, my goals, wants, and desires, in my head and ONLY in my head? Why am I not out immersed in the actual DOING of it? What's up with that?

What is it, do you think, that takes a cool idea like that sand castle by the beach... and transforms it into the actual reality of say, for example.... this?
