PSA: More estheticians are choosing their own work hours now

I keep hearing from people in the field who are swapping set shifts for solo work with open schedules. One person I know uses a simple online tool so clients pick times, and she only comes in for bookings. This lets her avoid rush hour or take a weekday off for a dentist visit. But it means she's now in charge of finding her own clients and keeping records. From my own freelance work, I see how nice it is to control your day. Still, it adds new tasks like tracking income and putting yourself out there. What ways have you found to make this style work without getting overwhelmed?
