What do you think is the most valuable lesson you learn from your parents? Or just the one that first comes to mind?

Preferably a positive lesson. I just want a positive question about parents to even things out here.

From my mom: There's more to life than being a productive member of society or just fitting in with the cultural norms in general, and having a different life than others doesnt make you less of a person.

From my dad: To focus on myself, and that negative feelings are not the same thing as negative thoughts.
