I think it is very normal, the world is freedom and competitive that everyone need to work hard to get what they want, you are free to get greedy and fearful as you want, the world is a machine that need to be running continuously without a pause, then the earth is stronger.
I agree of that. Every one need to workhard to get income to use in there daily life. Yes you are free whatever you want even greedy and fearful cause life goes on and the worlds are continues running you need to survive and to become successful in the future.
You need to survive and and use every skills that you have in order to gain much better, people who can handle the risk and capable of working out with others fear are going to benefits and make more success, as they can mixed up. There strategy and continue to profits.
