1. Figuratively (Conceited): You “carry yourself” with too much importance and an inflated sense of self. This is the most common, negative meaning.
2. **Literally (To be responsible for):** You "bear the burden" for yourself, without relying on others. This is a neutral, formal meaning used in phrases like `后果自负` (bear the consequences yourself).
This is the most common point of confusion for learners.
