Take the profession that is closest to your heart, to your true nature, swabhava and swadharma. Do it with sincerity in the spirit of serving Mother India. Be an example to others of what it means to be an Indian in the true sense of the word. This will be a much truer service than working to earn money and then use it for making the country great. Most people who try that generally get into the grip of money once they earn well and the idea of serving the country recedes in the background. So do what you can do best and turn it into service for the motherland.
Affectionately,
Alok Da
