I agree that to you true heroes makes us evaluate our lives, whether we do not come to regret what we do. Randy Pausch as I learned through you is truly inspiring person. He chose to make the last part of his life as something that could enhance each individual living on Earth to live achieving the best of their potential.Although, for me, it is not an easy thing to do but in the end it so much a worthwhile effort to do good generally and make inspirations to others to live by.
