I want to prioritize being in the place, where I can be most effective as a human being and contribute back to the humanity.
As a side effect of this I contribute back to the places, I care about. I donated to a school in my hometown (which as my as I love I can't move back to because it has power cuts for 22 hours a day in 120F summers). Send decent amount of USD to India and advise startup in Indian ecosystem.
If at some point I feel that I can be most effective being in India, I would definitely go back!
