Yes, our mind is a battleground and its on us what we want to produce. Just to satisfy our ego we do all kind of work even those which we know are not right but juat for aelf satisfaction and human behaviour we fall on wrong path. If we can control our ego then we can control the world. In a bollywood movie there is a dialogue in movie Singham , " Sab kuch karne ka par jaykant ka ego hurt nahi karne ka." It means Do whatever you feel like but don't ever hurt ego of Jaykant. Where jaykant is the leading negative character and he does all the wrong things to satisfy his ego.
