Dear Aspirant,
I understand your situation.
No job can guarantee you quick money. The rate at which your income will increase depends on your skills and abilities .
Generally after finishing MBBS it is quite hard to get into a good college for MD and then to pursue independent practice. The path is challenging and there is a huge bias towards people who have medical background.
But, if you are willing to work hard and prove yourself you can ensure that you'll always have enough money with yourself for your survival. You will be able to increase your income once you gain the trust of people.
Hope this helps.
