> Cosmetic surgery. Be brutally honest on what can take you from, say, an 8 to a 9. Guys like certain physical attributes, and in general may get you more attention even outside of a dating app.

This way lies madness. Do not do this. Seriously, screw those guys who are not interested in you at your current attractiveness level (whatever it may be). If cosmetic surgery moves you up one notch on a 1-10 scale and that is what puts a guy over the edge, that’s not the guy you want IMO.
