Having never been in the military, I agree with PB.
I have been in PP for less than 10 years. Could honestly retire completely in a nother 5-7 years, but won't. Things are different but not THAT different.
I can tell you that I 100% would do it all over again in PP. The job is fun and private practice offers a lot of flexibility depending on your skillset and group/AMC (not all AMCs are built the same way-- Somnia is NOT Mednax or USAP)
Now as for opportunities... there still are plenty.
Join, make partner.
Join make partner and sell.
Join an AMC with no buy in.
Work at an ASC.
Start a ketamine infusion clinic.
If you are really lucky... you work in the mountains with @Noyac
It ain't over folks...
Just last week I was given the opportunity to become a shareholder in an ASC.
In the end there is nothing like a well run PP ship, yet there are still opportunities out there.
You want security? Go into surgery and deal with clinic.
They will still need an anesthesiologist in the OR to do the cases they went to clinic for.
