Sometimes I fantasize about being a slug.
Really, do you want to be a slug?
I don't know, I guess I just want to be something different. I don't know why, I'm happy with my life.
You're probably craving excitement and variety. I think that happens to a lot of people who are in a routine on a day to day basis.
I am really not sure about that.
Even if you're happy with your life, you could still be bored with the day-to-day routine. You have nothing to lose if you try something new, and it may help you break out of your rut. You might even discover a new passion and find even more fulfillment in life.
