I enjoyed every minute of it. It was like building fine furniture. All the prep getting the boards planed and jointed, making wider boards out of 12" stock, using the mortiser and cutting tenons, cutting dovetails for all the solid wood drawers, making the cabinet doors, finding solutions to get all the angles just right.
I like a challenge. It helps you keep your wits about you.

Just remember what my father always said, " Half the people in this world are below average!", and everything in life will make a hellova lot more sense.
