This is an aphorism from my aphorism book.
대가리 잡다가 꽁지를 잡았다.
dae·ga·ri jap·da·ga kkong·ji·reul jap·ass·da
head seize-TRANSF tail-OBJ seize-PAST
Seizing for the head and instead catching the tail.
According to the book, this means something like “big ambition, small success.”
I feel like this could be a title for my autobiography.
