Here's my current one:

Is she a 4+? proceed, else desist

Is she ignoring you? desist, else proceed

Is it 60%+ likely she over 18 and below 29? proceed, else desist

Is there a risk of violence >30% if you approach? desist, else proceed

  1. You may not leave the venue without her or an approach
  2. If you approach, you may not leave the venue without a rejection
  3. You may never see her again. You may never earn her attention again. The woman of your dreams will be railed by another man unless you win her over first."

Exceptions: if you're tired or have another priority eg work, you can desist
