I have several, lots really

What’s a personal mantra or philosophy you live by?

Count your blessings

Be Kind

The Truth Will Always Out

Karma will get you ( what goes around comes around)

Judge not, that ye not be judged

Do unto others as you would have them do unto you.

Getting older can be a bit of a pain, on many levels. But what it teaches you is something else. Listen to the elders.
