negative too runs this WORLD

It's easy to fall into the negative side if you don't have a mind the strong enough to avoid all the negative staff. Once you come into that world, it's too hard to come out again if you don't have someone who helps you. But, the most important is to take decisions in your life. Decisions that avoids all the negative things. And if you fell even so, you have to take the decision to stop and to come out of all these negative points.

One way of looking at all these negative stuff you mentioned is to regard them as reminders to always be on the right side or the positive side of things otherwise suffer the consequence.
