Put Past Decisions On Trial.
Another form of focused questioning is what I call "Zero based
thinking." This method requires that you put every past
decision on trial for its life regularly by asking, "If I had
not made this decision, knowing what I now know, would I make it?"
If I had not hired this person or gotten involved in this project,
knowing what I now know, would I do it over again?
If the answer is "NO" to one of these questions, then your aim should be
to get out of the decision as fast as possible. Be willing to "cut your
losses," and try something else.
