一时激情一时任性
[yī shí jī qíng yī shí rèn xìng]
One Moment of Passion and One Moment of Spontaneity. The phrase signifies a fleeting nature characterized by bursts of intense emotion followed closely by spur-of-the-moment actions without overthinking. It could refer to impulsive decisions based more on immediate urges than on thorough thought processes.
