Serve selflessly, don't be after money alone, don't earn money through dishonest means, never give/accept cuts, euphemistically knows as referral charges; a time will come when so much money will be after you that you want to run away from money. Be patient with all your patients and give them also a hearing. Always adopt the principle, "A Patient is NEVER Wrong EVEN if he/she is WRONG". By adopting this principle, you will never go wrong in your practice or your life.
