I've been building with LEGO for as long as I can remember, and I still have most of my LEGO from when I was a child including the instruction manuals that came with the sets. The instructions for 1682 Space Shuttle is a bit worn, but still readable. LEGO was also my introduction to programming through the Mindstorms visual language and later NQC, which set the direction of my education and career path. It's been a big part of my life.
