If one has not suffered, one would not be happy.One only truly comes to appreciate their life if it has been marked by hard work and sacrifices. You discover how fleeting it is and how precious it is. Then you are not willing to throw away what you have worked so hard for, for nothing.
This is my biggest problem with drugs. This is why it is such a sin. Because people, who are can be sad in their comfortable, conforming lives, are willing to throw everything away... But I know what life is worth. And I can't stand to see it being wasted so.
