Another point I would like to make: Being dissatisfied with our current state and constantly striving for something better is what allowed us to survive as a species, but in this case it's not always the best for our emotional stability. Appreciating what one has, even the small things, does not necessarily equal to them being sheep. Similarly, always living with the anxiety of becoming successful does not mean that one is a leader. It often just means they care too much to prove themselves. The key to living a happy life is for people to go their own way without comparing themselves to others. One has to find a balance between being too content to be bothered to change anything in this world, and being too dissatisfied to be able to appreciate anything because the neighbor has it better.
