Mice are cute. I would like to be a farmer mouse, just living in a little home and taking care of a little field of grains, because it would probably be a very peaceful, tranquil life. I can imagine the interior of the home having a mix of old and makeshift furniture. As for a carpet, an old sack with a very light filling of dry leaves would probably be nice and cozy, like an extremely thin pillow.
I would be a cobbler, my shoes known for their comfort and durability. Eventually, I would marry the baker's daughter. Our son with a more religious deposition would eventually join a monastery, and our daughter would marry my apprentice. It's a quiet life, but a fulfilling one.

That escalated quickly.
I would be fighting a world war against cats.
