When making a decision, we need to be clear that decisions may not determine the outcome.
You may make a good decision, but still the outcome is bad.
You may make a bad decision, but the outcome may be good.
Of course, there would also be probability of good decision-good outcome; bad decision-bad outcome.
But the key is to be present. To make a decision with the best information that you have at the given point of time. The key is to make sure you get the most information basis to be able to weigh and make the best decision given the timeline.
Timeline is also key. If not, you would be stuck in a limbo where you can just choose to sit on it. Timeline can come from an external source (i.e.: Boss assignment deadline) or internal (i.e.: self assigned deadline)
Thing is, it is such a liberating concept, where you focus on what you can control, which is your actions, and not be paralysed with thinking about the results. You can make the best decision; example, taking a cab when you are drunk, which is the most responsible and good decision to make. But what if you get robbed on the way?
Point is, there may always be external factors that you can't control. Like how your actions affect other people. Like how people would react to your choice. Like whether if people would judge you. Like if the result would be the same with what your goal was.
So be present.
