HUDSON: Singer and songwriter Jesse Ruben has written a lot of songs about relationships. “Songs about relationships are great,” the Philadelphia native said. “But there are other things to write about, things going on in the world, things going on in your life.” And one of those things is helping others. Ruben, 30, who now lives in Brooklyn, N.Y., is spreading his message of doing good through his We Can Project, an initiative that inspires and connects students to the difference they can make in their lives, their communities and in the world. Ruben stopped in Hudson this week to talk to students at McDowell Elementary School and Seton Catholic School and to perform at Seton Thursday night. The McDowell and Seton students are working together to raise funds for library books for Barberton elementary students.
