Something I've heard from several private practice owners say is the key thing about it is adaptability. You have to be on top of a lot of stuff you wouldn't have to worry about as a hospital doctor. You are in charge of salaries, you need to hire the right team, you could hire someone who is terrible, employees get sick, quit, get fired, changes happen in the field that change your practice, etc.
I do private practice and I'm the medical director of an addiction clinic. I do some forensic work on the side.
The private practice is 5 days a week but one is a half day. The addiction clinic stuff is the other half day. The addiction clinic is largely self-running. I got an awesome team and they only have to call me on the tough stuff. The clinic also has room for rapid expansion and the owner told me he's got plans to make this a multicenter thing (it's already 3 sites) with dozens of sites in several states so the addiction clinic may in the future supercede my private practice.
Each of these things have brought me much more pay than usual work. My private practice generates much more money than the average or median income as a psychiatrist. The addiction clinic pays me 6 figures for a half-day of work but if a real bad and serious case comes in I have to be ready to work all day long on it. This almost never happens so part of that pay is the expectation of things could get serious. In the last year this only happened once and it was really the therapists making a mountain out of a molehill.
Personally both jobs are very fulfilling. I make good money and at the addiction clinic I'm mostly in administration offering leadership that they want from someone with experience although I do see patients because as I told them, I won't know how the institution's running unless I'm also on the field seeing what's happening. I liken my job to less of me being a clinician and more of me being like Gordan Ramsay coming to a train-wreck restaurant, fixing it, and then maintaining it. We're past the first 2 stages. Now that it's stage 3 it's easy and good money. The addiction clinic's leadership (minus myself and a few others) are also mostly ex-addicts that really give a damn and want to pay it forward. That was very refreshing to me to work with an administration that gives a damn.
The owner of the addiction clinic is a highly successful businessman who wanted to divert a large sum of money into a dream addiction clinic cause his own journey to going clean was something where he wanted others to get the same experience. I was hired because one of the top addiction therapists in the area specifically recommended me. Which is why I tell people always do a good job. Aside that in our field where we heal people this is ethically mandatory it can pay off bigtime. I got the problem now of being very comfortable or taking to the next (likely stressful level) of being a part of a rapid expansion into something that could become several states-wide and working with some very powerful people in this process. I'm a bit wary about this cause I'm enjoying being a father and having time with my family.
