If you are not using your critical thinking skills throughout your whole life, there's a possibility that you may not be able to decide properly for the choices offered in your life. There may be a possibility that you might choose wrong decisions in life which could not be good to you or not helpful to you in making your life better. For example, if you are in need to choose what career to take, critical thinking is badly needed in that state. You need to balance out the pros and cons in every choice and without critically examined these choices, there might be a possibility that you might choose the wrong career.
