The reason the best businesses get hired is that you have the chance to make these people happy. And this is something that I think is especially important in the case of a new business, because the more money you spend on the job, the better you are going to make them happy.
You can think of happiness as being happy with yourself. This is one of the oldest and most well-known ideas in psychology. In other words, happiness is based on the fact that if you are happy, then you are more likely to feel good about yourself. More often than not this is just a myth or a myth-like idea that most people believe without really understanding the science behind it.
