Shikata ga nai (仕方がない): there is no way to do it. Nothing can be done, and there is no better way. Another dictionary adds: it is not satisfying, but there is nothing to do but give up.
Gaman (我慢): enduring, holding out, patience. As a Buddhist term, it means one of the seven kinds of pride: a self-centered mind that clings to itself and looks down on others.
