You Need Structure in Your Life

You like things to be structured and decided. You want to know what's going to happen.
The unknown makes you very nervous. If you know something is going to happen, at least you can prepare for it.
You like to have a plan A, a plan B, and if possible, plans C and D. Even if you can't plan for everything, you try!
