What's something you think you should do less of?

I think I need to worry less 걱정을 줄이다. I usually tend to worry about things that haven’t happened yet 아직 일어나지도 않은 일. Like exams, presentations, future job that are far away. I want to worry less. When I worry about something, it’s hard to sleep on time. I always think about the worst -case 시나리오 최악의 상황까지 생각해.
