Your parents learned things the hard way so you don’t have to. You’ll still learn some the hard way anyway.

Advice handed over carries the conclusion without the experience, and some lessons will not transfer in that form. Your parents can tell you what a bad job or a bad friendship costs, and the words will sit there politely until the day you meet one yourself. That is not stubbornness, it is how certain knowledge works. Some of it only installs on contact.

Take the inherited advice where you can, since it is free and sometimes it does land. When you do learn one the hard way, say so out loud rather than hiding it. They will mostly be relieved, and the conversation afterwards tends to beat the warning.
