自勉 is a verb meaning 'to exhort oneself' or 'to encourage oneself.' It combines the characters 自 (zì), meaning 'self,' and 勉 (miǎn), meaning 'to make an effort' or 'to encourage.' Together, they express the intentional, inward act of motivating oneself—often in the face of difficulty, doubt, or stagnation. It implies personal responsibility for one’s growth and reflects a Confucian-influenced value of self-cultivation.

This word is commonly used in reflective, formal, or literary contexts—such as diary entries, motivational speeches, essays on perseverance, or academic writing. While it can appear in spoken language, it carries a slightly elevated, earnest tone and is rarely used casually among friends. It often appears after subjects like 我, 他, or we, and may be preceded by adverbs like 时常 (frequently) or 不断 (continuously) to emphasize ongoing effort.
