" If you view life at 50 the same as you did the same as you was 20-you  have wasted 30yearsof your life."
                                      Muhamad Ali
My opinion is that if you did then he is right, because he is saying that things change. LIFE CHANGES!!!!!! You could have had a family,a job, a house. THINK ABOUT IT! Do you want to stay the same, you will probably end up with nothing. Years past by fast, so don't waste it :)
