New York - A US university has released excerpts of letters written by a young Barack Obama to a girlfriend. September 1982, New York City"I must admit large dollops of envy for both groups, my American friends consuming their life in the comfortable mainstream, the foreign friends in the international business world. Caught without a class, a structure, or a tradition to support me, in a sense the choice to take a different path is made for me.""The only way to assuage my feelings of isolation are to absorb all the traditions, classes, make them mine, me theirs. Taken separately, they're unacceptable and untenable." June 1983, Indonesia"I can't speak the language well anymore. I'm treated with a mixture of puzzlement, deference and scorn because I'm American, my money and my plane ticket back to the US overriding my blackness.I see old dim roads, rickety homes winding back towards the fields, old routes of mine, routes I no longer have access to." (AP) November 1983, New York City"Salaries in the community organisations are too low to survive on right now, so I hope to work in some more conventional capacity for a year, allowing me to store up enough nuts to pursue those interests next."April 1984, New York City"My ideas aren't as crystallised as they were while in school, but they have an immediacy and weight that may be more useful if and when I'm less observer and more participant."
