Not Enough Time and Client Schedule Assumptions

I work a job during the day 3-4 days a week and my aim is to fill my coaching practice this year with 10-15 clients per week. 2-3 days/week I am available to work with clients during the work day. Because of mental and physical health care (I’ve worked with doctors on this), I customarily stop working at 5:30pm to wind my body and mind down in order to get adequate sleep. I start my work days between 9:30-10am. Because my coaching niche is people who work traditional work hours 9-5, I’m worried that I won’t be able to keep my health schedule and build a client roster.

Even if they have the money to work with me they won’t be able to during my preferred hours because they are working.
They will choose their jobs over coaching.
I’ll be stuck at my other job for another year because I’ll have to say no to these clients.
I refuse to work after 6 PM.
I’ll have to say yes to coaching these people from 6 to 9 PM and then it will all fuck up my sleep.
I need to be willing to do whatever it takes, including putting my business over my self-care.
My sleep is priority number one.
My sleep is way too sensitive and I’m not gonna fuck with it.
If I say that I can only coach clients between 10:30 AM and 5 PM, 2 to 3 days a week, take it or leave it, the clients will leave it and I won’t have any clients, or maybe one or two.
People won’t adjust their schedules to receive coaching during my availability.
If I have a beginners mind, I need to be willing to do whatever it takes to fill this practice, even if it means fucking myself over healthwise.
I’m scared to decide that I’m not willing to sacrifice my nighttime care and my morning routine for anybody, not even my business.

I ran a few models with the T-lines of “ I won’t have time for clients without stressing myself out.“ and “My clients will only be available to work with me after hours.“

The R-lines were “ I don’t make time to market effectively. I stress myself out now.“ and “ I don’t make myself available to work with clients now.“

I’d love to believe that (a) I can make this transition easy. (b) I will have the time to fulfill my wellness needs and add clients.
