Personally, there is nothing more satisfying than the art of creating an object by hand. You could build a dog house, craft a gas tank out of sheet metal or even do a killer hand painted sign, but in that process of bringing something new to fruition, there is a feeling of satisfaction of a job well done that tends to permeate the finished task. Next time you are building something or looking for ideas, don't rush through to the finish, maybe think on the old traditional ways of doing things and have an appreciation for craftsmanship.
