I have created (built) stuff, physical things in this lifetime.  I created many small things and some larger ones like 4 houses, an amphibious airplane and a 40 ft. ferrocement sailboat, powerboat and more.  All have been sold except the last house that I live in.  I also realised that while creating a thing like a boat, one create many smaller objects in the process, some smaller objects are inventions in itself.
