Potentially a silly question: I was watching this video and heard this. It may be because I'm not a native speaker, but I believe I haven't heard it before? All my searches lead to the word 'inhibition' which is more or less the opposite of this definition. Any clarification of what Candice said/tried to say there, or any alternative words?
have the courage of one's convictions, to act in accordance with one's beliefs, especially in spite of criticism.
(I'll note that "have the strength of one's convictions" is more familiar to me, but some sites suggest that it's archaic.)
