YSK: There is nothing wrong with reminiscing and being proud of yourself but don't get addicted or too comfortable with seeking a lot of gratification from past accomplishments or good experiences. It might prevent you from making new accomplishments and good experiences.
from /r/YouShouldKnow
YSK：回憶和爲自己感到驕傲沒有錯，但不要沉迷於或過於舒適地從過去的成就或良好的經歷中尋求大量的滿足感。這可能會妨礙你取得新的成就和好的經驗。
