How to say "Self confidence" in Japanese

When translating "self confidence" into Japanese, you must choose carefully between 自信 and 自負. In Japanese, 自信 (じしん (jishin)) is typically associated with "self-confidence; assurance; belief in oneself" (Syllabus Level: N3) and represents Refers to self-confidence, assurance, or holding a firm belief in one's own abilities or the correctness of one's actions. Often used as 自信を持つ or 自信がある. ⚠️ Haruka's Voice Column: 'Self-confidence! 'I have 100% confidence to make Haruka happy!' ...っ, T-To say that with a straight face, you've grown bold! B-But keep that confidence forever!' / 【ハルカ部長のワンポイント指導】『じしん（自信）よ！『僕にはハルカさんを幸せにする100%の自信があります』なんて真顔で言うなんて、生意気よ！…でも、その自信、一生崩しちゃダメだからね！』. On the other hand, 自負 (じふ (jifu)) maps to "self-confidence, pride (in one's abilities)" (Syllabus Level: N1) and represents A sense of pride and confidence in one's own abilities, skills, or achievements. It's a justified pride, not necessarily negative like arrogance.. A literal translation of "self confidence" can often sound unnatural to native Japanese speakers if mixed up!
