SQRT, indeed, being able to be an independent business owner. There is a big thing. An eved is a person who does not control his own time. So, when you are an employee, you are to a degree an eved. And, in most companies, eved knaani .. or l’knaani, needing to go ask nicely for an early Friday or yom tov off. Some people enjoy explaining shmini atzeret to a Hindu, I don’t. So, as a self-employed you will be working 24/7 – but not in a row.
Of course, make sure you have math and business skills and know and can follow halochos of honest weights, etc.
