Been a while since I've used legos, but i always notice that when I actually made something myself with my own 2 hands, it gives me an immense sense of joy. It's a huge step away from some of the college classes that were mind numbingly boring. But making things from wood, or making custom clothes with a needle and thread, making a cool piece of art, getting into that flow state and being able to tangibly experience your creation is something that certainly gives me a reason to live.
