<p>Probably owning your own specialty business - surgery, etc.<br>
I was in practice for a while. Sadly, I have to say that I was not cut out to own a business. Loved the medicine, hated collecting past due bills and really became disheartened when people didn’t pay me and/or complained about fees.
I quit working to raise my family - now I’m going to nursing school so I can have a job with benefits, flexible hours, and nobody complaining about my fees. 
I LOVED veterinary school and the people there – I just wasn’t cut out to own a business.</p>
