Establish Plan on how to get a lot of referrals - Public Relations Campaign

Establish Hospital Privileges in very reputable Hospitals

Market yourself....attend  Rotary, Lions club, barangay meeting.  Bark up the right tree. If you are
an internist, then you  could promote yourself with  the seniors. A pediatrician  should attend  school meetings.
Have good  management systems for your office: a good receptionist, assistant/nurse, billing  person.

Start a practice  with  less competition  and high barriers to entry.  MetroManila, LA    have an oversupply of docs.

Maintain good quality:  continue  studying  and keep up.

Maintain access:  Try not to go on 2 month vacations  in the first few years.  Your patients cannot wait for you

Multi-task: you can be  a hospitalist, office doc,  teacher,  researcher  at the same time
Leverage technology: set up a lab, Ultrasound, Holter, Pulmonary Function Tests, etc
