There are two times to admit mistakes: early and late.

˃˃˃ Early admissions solve problems.
˃˃˃ Late admissions create them.

A person who proactively tells another they made a mistake gains trust and respect for their honesty. In contrast, one who tries to hide errors quickly loses trust.

˃˃˃ Swift admissions build bridges.
˃˃˃ Slow ones burn them.
