Final answer:
The phrase reflects a realization that with age and experience, one must be honest with oneself rather than pretending to have honorable intentions that are insincere.
Step-by-step explanation:
The phrase "I'm years too old to lie to myself and call it honor" suggests that the speaker realizes that pretending to uphold honorable intentions while deceiving themselves is no longer justifiable due to their age and experience. As one grows older, they often gain wisdom and self-awareness, recognizing that maintaining an exterior pretext of honor without inner sincerity is a form of self-deception.
The idea behind this statement is that with maturity comes the responsibility to be honest with oneself about one's motives and actions, rather than hiding behind noble-sounding yet hollow rationalizations.
