Same here. I am positive that it was Lego that influenced me to become an engineer. Ever since I was a small kid I just loved building stuff. Making something out of almost nothing, with most of your creation backed by the power of your intellect is something that is very special. After I outgrew Lego, I started building cities in Sim City... and shortly after that I started coding. It's a logical progression, isn't it?
Plus, for me there literally was something magical in Lego. Every new set would bring such an unparalleled amount of joy and happiness that is hard for me to verbalize now, but I can still vividly remember that feeling of getting a new set and just feeling ecstatic about it... ah, the childhood.
