Accept that you always have a choice
We do not always have the choice we would like, but we do always have at
least one that allows us to take a position with respect to the
alternative. "Yes or no." "Yes under this condition
or no under that other condition." It is not the absence of a
choice that is a problem, but rather our fear that our choices will have
consequences that we won't know how to face. And when
those around us perceive that we have not staked out a position
to defend... they occupy the terrain that we have left open.
Clearly define the possible options (even the "bad ones")
By establishing the different options that are possible or not possible, we do not yet make a decision but we formalize the various ways forward and their potential consequences. We thus become able to explain them to our pressing interlocutors (who thereby understand that we have the situation in hand) and also, generally, to take a position. For the issue is not to take the best possible decision but to take a position and to know why.
And one approach to follow: talk about what is possible, even if you haven't deicided yet!
Even under pressure, you have the right to ask for time to think, to analyze, to discuss together! And for that, you also have the right - the duty? - to demand the confidence of those around you: "I know what I'm doing", "I have good reasons to..." If this confidence is lacking, then it becomes the principle issue to deal with.
