As my FT username suggests, I like the idea of lifetime memberships. See my profile.
Having obtained the highest lifetime status currently offered by Marriott
BONV°Y™, I have given up that chase and am now focused on helping my wonderful spouse of 31 years obtain that same lifetime Platinum Elite status. 💚
Five years and ~200 nights to go.
In a similar vein, if your U.S. career income was significantly higher than your spouse's, it is best to wait until 70 years old to collect Social Security, to maximize that 50% spousal benefit (at age 67, for those lower-earning spouses born in 1960 or later).
I'm not sure I will ever attain lifetime UA Premier Gold status (1MM), but that is not a dream I am willing to forego.
