I have 2 businesses and I can tell you that you need to put the time in it . However I do not think you need to put 60 to 80 hours a week in it. You need to be prepared and organized those 2 things are very important. You need to have a good routine how you do things. On occasion you might need to work those long hours. But if you have a good work routine you should be able to work 40 or 45 hours a week.
