The ramp-up period can be challenging. You have to work extremely hard, especially when first starting to ramp up your business but if you work hard & persist, your business can flourish rather quickly (within 3-6 months) in my opinion. It's also the type of business where you can set your own hours but the work never stops, you could work as much as you want which can be a good & a bad thing. You need to set your own boundaries for work/life balance.
