It is good way to finish the job, and solve the problems. Network of “friends”. Not friends that you can count on in some life threatening situations, but people that you can count on when you have some problem to solve.
It is very hard to live alone, without connections with people around you. You simply need to be connected with those people from different areas of life. I know, and have those connections with many people, some from criminal “side” other from police force, it make sense to have good connections and information from different areas.
Real friends are maybe one or two, but there s other folks who can help you a lot.
