我不是你想象的那么勇敢
[wŏ bù shì nĭ xiăng xiàng de nèi me yŏng găn]
'Not As Brave As You Think' reflects a modest or self-deprecating outlook on one's own courage. It implies that while someone might believe the person to be very courageous, they themselves feel less so. It carries humility and realism about personal limits.
