We have psychological or mind responses which was very useful for survival, when we were living as Hunters. Those responses or behavior were genetically programmed.
Then, we were farmers did agriculture, them we were industrialist and today we are somthing.
But those genetically programmed psychological responses still prevail in present days, but they are not needed now.
Our mind is genetically programmed to jealous, greed, fear, desire for survival. They are survival instincts for the living style of past era. Now they are not needed, but we still have them and follow them blindly.
We have to cheat our gene code to not to have jealous, greed, fear, desire in present day living style.
We have not given sufficient time to evolution to reprogram or upgrade mind as per present days.
We live in silicon civilization, but we have and follow the mental reflexes of stone age hunters, like ferociousness of lion in zoo and betta in bowel.
We have to cheat our gene code as far as mental instincts.
