Fortunately not all young people are like this. However I've seen some young people, who I know well, who are very prideful, who think that they know it all, and won't listen to advice. They have seen other older adults do many things with seeming ease. Consequently, these young people think that many things are easy, that they can do anything without much effort: They know how to do it! However, when they do it themselves they try to make a quick job of it doing the project and make a mess of things. They get angry and grumble about this or that, about something not being right.
As a result of their often impetuous and unthoughtful actions and attitudes they can cause many problems for themselves and those people around them. Then they are full of blaming and accusations for everyone but themselves. They refuse to believe that the mess they are in is of their own doing.
What they don't realize, and don't want to know, is that the older adults may have spent many years learning how to do projects and to live life more efficiently. Many young people don't have the skills and often don't want to take the time to learn. Consequently they make life much harder than it needs to be.
