The fallacy of giving advice is that what works for one person rarely works for another.
Advice is unique and personal, a collection of warnings we tell ourselves about how to avoid past mistakes, synthesized and abridged for a recipient.
“Unsolicited advice is the junk mail of life.”
Bernard Williams
The best advice we can give someone is to encourage them to develop their own opinions of the world. Our experiences are neither guides nor answers; everyone deserves the freedom to their own way.
