text: Making a tough decision is much easier when there are people to tell you what mistakes they made. When you know about what they did wrong, it can help you avoid it. Say that you do not know which product to buy. Your friends all say that one product is better, because their product broke and is unusable after a short period of time. Making the decision about what to buy is no longer difficult, because you have the advice of people faced with the same decision, and when you heard about their mistake you avoided it. By asking your peers, you made a good decision.
