Wrong decision

We have to make all sorts of decisions everyday. Some are easier than others. What causes you, or anyone, to make a “wrong decision?”
For this discussion you need to give an example of a decision you made and wished you had done something else. This could be a personal or professional decision. What factors caused you to make the choice you did?
I am not trying to make you feel bad here. The best way to become a good decision maker is to look at past decisions we have made. When we better understand why we make poor decisions, then we are less likely to make the same mistakes in future decisions.
