deal breaker method

i'm habitually single. maybe insistently. or tragically. who knows?

i meet interesting people all the time, luckily, but there's nearly always something not quite compatible. a 'deal breaker', if you will. i'm sure you will.

i have a simple 5-step proposal:
1) list all those deal breakers - get a piece of paper and a pen. or open a new text file. it'll be quick, i promise. 
2) pick the most important three items - the rest are garbage. who are you kidding? you're being ridiculous with all those demands, pick three.
3) print your calling card - it's cheap as hell, order like 200 of those things printed with your three deal breakers (under the header DEAL BREAKERS), and name and email address and/or phone number. giving a physical card is classy. (i find email is less creepy than phone calls from unknown numbers. you can email a phone number. clearly, do whatever you want.)
4) met some potential partners - you're already doing this, probably, just keep doing your thing. hand out the card when it's contact info time.
5) they contact you (or don't) -  whatever, it's their loss. you would have found out they have a ferret (or smoke cigarettes, or live with their mom) eventually, you saved the both of you a lot of time and agony.
5b) go give out some more of those cards - you have a ton of them just laying around.

so, can we do this single people? i'm more than a little frustrated with dating someone for 3 months before i find out they're irreconcilably intolerant of something i can't live without. or vice versa.
