You Are a Donkey
You have a reputation for being stubborn, but that's okay. Your stubbornness has served you well in life.
You know what you can and can't do, and you resent anyone trying to push you. You like make changes on your own schedule.
You are a very conscientious creature. You are willing to take responsibility for yourself and for the people you care about.
Because you have a lot of burdens, you have to be extremely careful and cautious. This explains your "look before you leap" mentality!
