将就惯了不愿将就
[jiāng jiù guàn le bù yuàn jiāng jiù]
This reflects a mindset transformation from accepting mediocrity in the past to now aspiring for better experiences or higher standards. Literally meaning 'got used to compromising but unwilling to compromise anymore', it implies dissatisfaction with what one has tolerated over time and a desire for change or improvement in various aspects of life, such as work or relationships.
