It's your decision to decide between the two options base on your interest and personal conviction but as for me, i will advise that if you're a salary earner then you must find an alternative to that as an independent source of income but if the work which you do gives you no reason to fo other menial jobs and the salary you get does no commensurate with the effort put altogether, then it's advisable to quit the job and remain independent provided you have passion for an independent job, also try to make good branding to your enterprise in other to make it attractive to customers, engage on business seminars and kearn how to be a successful entrepreneur and you're fine.
