Having a stable job or owning a business, both have perks and downsides. While business offers you independence, you need to deal with a lot of responsibilities for owning a business. If you have a job, you will have a stable income and need not worry about additional responsibilities.
In terms of qualifications, if you own a business, you don’t need a lot of qualifications. You can get an MBA and learn business or learn it from a mentor. But, when it comes to jobs, you need to have specific qualifications. It can be an educational degree and years of experience, which is not a prerequisite in owning a business.
In any manner, to do a business or job, it is up to your choice.
