Focusing on choices that essentially affect only the chooser:
“If you’ve never been mugged, you’re taking too few alleyway shortcuts” would be terrible advice, whereas “if you’ve never been turned down for a date, you’re not putting yourself out there enough / aiming high enough” is generally good advice. So now we are talking price.
Setting aside that doing things that are bad for ourselves is often bad for others, and looking at the specific example offered: To me, missing a flight would be like getting mugged. Or at least, it would be much more like getting mugged than getting romantically rejected by a stranger. If it’s a thing that happens once in my entire life, then I haven’t spent enough time at airports.
