There's nothing wrong with working a 9 to 5 job if that's what pays your bill. People who talk down on people who work a 9 to 5 or multiple jobs are probably jobless or just critics. Life is in phases, not everyone is going to figure it out easily. If working this type of job is a start for you there's absolutely nothing to be ashamed of, all you need to do is plan for a better future, save up to start up your own business because being self employed is one of the ways to facilitate success. As long as you are not planning to do such a job forever then there's nothing wrong about it.
Not everyone can do business, and there are a number of reasons for this. Some may not have the aptitude to do business, many would not have the knowledge and money to do business. Others may not be willing to take risks in business and are more complacent with the 9-5 job-granted income.
While a Job can give you limited income, a business can allow you to make unlimited money. However, business does have more risks, and sometimes, you have to face losses too, while in a job there is no concept of negative income.
