I distinctly remember that I was in pre-school, though I am unsure of my exact age. I was building a block structure for a red foam ball to roll down. I remember that I was trying to talk to a few other kids to help me build the entire contraption. Looking back, I still feel like that's who I am today. I still feel like a little kid trying to build fantastic contraptions out of nothing but blocks and a wild imagination.
I also feel a connection between myself at the age of my earliest memory and who I am today. My first memory was of getting my first pair of skis and learning to use them. Your passion of building things seems similar to my passion for skiing. It seems like to a certain extent the things a person enjoys can be carried with that person throughout their lifetime even if their personality grows and changes as they age.
