Don’t be in such a hurry. Learn a little bit more about a specific country or culture, a specific sector, the complexities of global poverty and long run economic development. At the very least, make sure you are sound on just plain economics before deciding how you personally can contribute. Be willing to accept that your role will be specialized and small relative to the scope of the problem. Aside from all this, you probably already know better what you can do than I do.
But I do salute you again, and I do believe when there are enough people like you, you will cumulatively make a difference.
