If possible, I would encourage new business owners to hold on to a full-time job for a while, until their new business takes off. If you have a full-time job and you're starting a business, the first thing that usually comes to mind is quitting your job in order to pursue your business. Many types of businesses, especially online business, can be started and grown part-time. Holding on to a full-time job for a while will reduce financial risk, allow you to have more patience, and reduce stress.
