The variety of scams that people play on each other are numerous and creative and abundant. So, there are tricksters, or perhaps, a little bit in each of us. We like people who are happy, friendly, and cheerful. It is not enough to fake it, although to a certain degree, given that we are all experiencing some degree of discomfort, we all put on our best face. By doing that, we create the positive energy to sustain ourselves and others.
Happiness comes through creativity and productivity.
You must use your imagination to create, to build, and through the productivity you will find happiness. You must realize that if you destroy or constantly complain, you will never be happy. Constantly work to develop your own career. Ultimately, it will be a great possession and the source of great rewards if you attend to it properly. If you come into a position of power, don't abuse it.
