Question

what negative qualities have we removed from us

Answer 1

The best way to remove negative qualities from our attitudes is to analyse ourselves.
Just think what are you doing in respective of other person.Like, when are you deciding something or taking any decision or doing anything regarding someone then first think by placing yourself at that person and try to make that person not feel bad.
No one is perfect always remember that so don't always try to make that person happy, if something right will make someone feel hurt then its better to make them hurt rather than making that one person feel good and after sometime every bad decision will make a lot of people feel bad so after thinking about that one person if some point that decision is not good don't take that way.
Always there is a way for every problem a way in which we can do better 
for everyone. I know i do not qualify for these things to tell anyone, but truly these are my own thoughts towards a better world.
