Work for a charity for 6 months. And not in a back office role somewhere spending each day at a computer. Go and work directly with the underprivileged, the homeless, the sick or the poor.
This will shape your future career by providing a solid foundation of empathy, leading to stronger relationship building skills and hopefully an ability to better communicate with people from diverse backgrounds in a wide range of professional situations. You will be much better placed to succeed than the graduate who has never taken time to explore life and themselves, outside their immediate surroundings and social circles.
