How to stop believing # of hours = dollars

Hi Brooke and coaches: Thank you so much for all your work. My question relates to the money module and business. Here goes: If I go all in as a childbirth photographer, I will offer my passion and expertise at capturing these precious and fleeting moments. It’s hard for me to see how that doesn’t turn into me thinking the equation # of births per year = x dollars I need to make. The more births, the more money. That seems like the same mindset I’m in now of more hours worked = more money. What am I missing as I conceive of my new business mindset? Thank you!
