Everyone's got to have some hobbies to fill up their spare time. Most of us are willing to spend money on our hobbies. That is perfectly fine. But, I think it will make much more sense if I can earn money from my hobbies.
My hobbies are related to managing my own money - growing my money(investing), protecting(insurance) and maintaining(saving, spending wisely) it.
The most respectable way to earn money is to become an entrepreneur. He is someone who enriches himself while enriching the lives of others by creating new products/services for his customers, jobs for his employees, business for his suppliers and wealth for his shareholders. It is hard to be jealous of the wealth of such an entrepreneur because of the value he creates to society. As of now, I will prefer to focus on the activities of managing my money.
