text: If you were planning a vacation and you couldn't decide where to go, you might ask for the opinions of people such as you family members or people who have traveled the world and might know a good place to go on vacation. You might never have been to Hawaii, but someone you know has, and they tell you that Hawaii is a great place to go on vacation. After asking around, you get lots of recommendations to go to Hawaii, and people give you lots of ideas on things that you could do while your there. You feel much more confident in your decision to go to Hawaii than you would have been had you not gotten so many recommendations to go there. The ideas and opinions of other can be a very helpful tool when you need to decide on something.
