to do something uncertain, trusting that it will succeed
何か不確かなことをする、成功することを信じて (nanika fukakuna koto o suru, seikō suru koto o shinjite)
"Starting her own company was a leap of faith, but it paid off."
"自分の会社を始めるのは信念の飛躍でしたが、うまくいきました。" (Jibun no kaisha o hajimeru no wa **shinnen no hiryaku** deshita ga, umaku ikimashita.)
