Seems like the goal of “human rights/nonprofit work” is nebulous at best. What human rights? What type of work? Just being a body holding a sign for anything isn’t really much of a goal. Have you formed specific goals and do you have specific skills (rather than “I’m a really good person”) that could increase the likelihood that you can impact? Do you know enough about water, regulations, geography to help people living in poverty in countries where access to clean water is restricted? Do you know enough about the political word of Western Africa to know what efforts might help but which might simply line pockets of corrupt leaders? How is your advanced math? Can you help with epidemiological studies of population growth and food access (to address some agricultural issues)? Having specific skills is far better than being good at joining a march. What skills do you bring to the fight for “human rights”?
The message the OP gives off is that she/he is done with formal instruction and knows enough to pave her/his own way. I applaud students’ efforts to do independent work. But that isn’t the message I get from OP. Seems more like she/he is above having to learn from others and above classmates as well.
Maybe Yale isn’t keen to have students who are not interested in learning what they offer but feel they have already mastered it and are ready to move on.
to OP, your list of colleges along with your statement seems to scream “fuzzy thinking”. You are at risk for avoiding all courses that would provide you with skills in favor of courses that allow you to discuss generalities and theory. Consider what skills you bring to any job-being a “good” person won’t help one bit if you have no skills to bring to the table.
