4. Well, from what I've observed, it seems to be very difficult for us to keep everyone happy at the same time. The reason is that different people have different opinions about the concerned thing/matter. And generally these opinions also tend to change from time to time due to certain factors like circumstances/certain incidents/certain influences. So, in a group of, let's say, 6 people, even if you've ensured the happiness of 4, the other 2 are going to be unhappy & if you are lucky enough, then they might be unaffected & not sad . If you try for a midway solution, then everyone will be partially satisfied but then again they may feel only satisfied, not happy.
5. Man has a inherent instinct to control somebody. This somebody can be either himself or others. Trying to control oneself is very difficult then trying to control others. A man is justified if he tries to control himself & not if he tries to control others. The Society is formed by such people who can't control themselves & so they try to control others by interfeting in others lives either directly or indirectly (by inflicting posinious remarks/gossip) .
6. The concept of Society is definitely good as long as it protects the positive/benevolent interestes of an individual & not victimize him/her.
7. We need to have some proof if we want to convince others cause they have to be sure that we are telling the truth & have a valid reason to say the particular thing. But if you don't worry about convincing others & say things truthfully, then you don't need any proof. Cause you know you are telling the truth & so it shouldn't affect you if others believe you or not. The main thing is that you have to be Honest to yourself to eliminate any feelings of guilt. In such case, others belief on you will depend on their trust on you.
