I wouldn't say that those factors are dangers of being a serial entrepreneur. But those are challenges that one has to take upon deciding they want to be an entrepreneur. It's not an easy path to be one but, once you succeed. You'll definitely feelng that you're one of the chosen few to take that route. It's time consuming because it is your business, it is your enterprise that you are building and not someone else's. At the beginning, you'll have to understand how your system works into your business until you can delegate that and when you're already profitable.
