It is important because, without feedback, the teens would not know if what they are doing is correct, wrong, needs improvement, should be done a different way, etc. An individual needs to know these things in order to adjust their behavior/techniques and improve. Otherwise, the individual continues repeating the same process over and over again and getting the same results, and if these results are bad they will never get better and progress in life. That is why it is extremely important that adults give feedback to teens.
