It is important to know what one’s preferences are and try to implement these as much as possible. But there is wisdom in letting the situation decide for you. This is because we only imagine we are in control of things but in truth there are a lot of things outside of our control.
The way to peace is to understand what the moment is asking of us, not what we are asking of the moment. This may entail relying exclusively on your own decision when it is impossible to obtain others' inputs or soliciting others' opinions to gain a more complete picture of what the situation is calling for, before coming to a final decision.
