Power
When you drop the hammer on someone, it will be in the literal sense only. (Be sure to apologize.) The power you wield will be pretty much limited to the furniture you put the screws into and the boards you keep in line.
Your first job will either be sweeping the floors in a shop where you hope to someday learn the craft, or as an assembler in a plant. You might also operate a machine that cuts the various pieces to a prescribed size for the assemblers. It's not terribly challenging, but you have to start somewhere.
If you master the trade and show a flair for design or antique restoration, you could be influential as a furniture maker that specializes in unique creations. That kind of influence can translate into a whole new kind of power: power over opinion. Your clients will depend on your sage advice for what furniture would best fit their homes' décor, and you'll be able to give it to them.
They might even consider you to be an interior design genius; and if that's the case, you can dish out that advice with a worldly air of exasperation. Not many people have enough power to treat their customers with anything less than full respect, but interior design geniuses get a little break. They are geniuses, after all.
