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.
Greed never leaves you out at any stage of life. When you dont have money, you are greedy. You are getting something slowly and gradually and you are greedy. You are quite rich now and you are still greedy. Trading or investing isnt hub of greedy. Unlike gambling where everyone is greedy and everyone is looking for more money. Dont lose your motivation and get your results.
