We have so many people in our lives who went through failure and pain and they are ready to share their experiences with you, why aren't you ready to listen to them? Is it much of a big deal? Taking advantage of other's mistake is not evil, it's wise IF your aim is true. All you have to do is not repeat the same foolishness and face the same pain that they did, simple as pie but not π. There are two ways, either waste your time is stuff which is not even productive or make the most out your time. Your Choice!
