Like the author said, the world is a mixture of good and evils. It is our decision to choose which one. Around us also there are people who pretend well in front of us and internally they might want to see our downfall. They are clever enough that they can make us believe and trust them. If we ever listen to their words and do things as per them, later we will be in trouble as their ultimate aim was not our success. We have to use our own thinking ability or brain before blindly listening to anyone, no matter how much trustworthy he/she is. No one will be there to face the consequences of our deeds or decisions so we have to be careful. Those who stand beside you even during your bad times are the real friends and not the one who is trying to put you into troubles.
