Put an End to Waffling Over Decisions
If you're second-guessing yourself about a choice you just made, head for the sink for a quick regret-rinse-off. Recent research from psychologists at the University of Michigan found that the simple act of washing your hands can help you to stop questioning your judgment. While the decisions being made in the study were trivial—ranking preference of one CD over another—this act of "cleaning the slate" by washing your hands may work to help you gain confidence in the bigger choices you encounter, too, like deciding which car to buy, or when to have a difficult conversation.
