That is very true. If one wants to be financially successful, often times the main solution is to build a business.
Some people even work jobs and then their end goal is to have a business and make profit from there. The reason why I think entrepreneurship is so attractive to a lot of people is because you are your own boss. All your profit is yours to keep and any creative decisions shall be made by you. I also want to establish myself as a successful entrepreneur someday.
Business gives you extra income and one who is doing a job when use his salary little by little to settle a business then in no time he will become financially stable and he will not think about spending and will not be in stress when he fulfil his family needs.
Other main thing is that people having Business has created the way of earning in advance for the age when he will not be interested in doing job or will not be able to do so because human cannot properly work in every age for his family and after some years he want retirement from work during which he can earn well from Business.
