The most stressful situation we can find ourselves in is one of indecision. We just know which decision is the right one where the outcome is not certain. We can end up suffering from ambiguity.
We make a decision at 10:00 o'clock and at 10:30 we revisit the decision and decide the other way and so on throughout the day. We just are of committing to one decision or the other.
The problem becomes that no decision is still a decision and we can end up running out of time and we could become overrun by events that take the decision away from us.
Sometimes we simply have to stop looking at consequences and look to what small action we could take that would help us decide. Instead of deciding by guesswork we look for that one piece of information that will help us decide. in this way we get out of the problem box we have put ourselves in.
