There's nothing intrinsically wrong with talking over ideas of where to eat with friends. It doesn't mean that I'm living my life wrong.
But let's just say for sake of argument that it's best to always be random and spontaneous. Tonight, you should randomly pick a channel on TV, and watch it. Or randomly select a movie. Maybe you don't watch TV or movies. Then a random book off the library shelf?
I do in general terms like your suggestion about being spontaneous, and living in the moment, and embracing chaos and randomness. And here's a suggestion for you: don't tell other people how to live; it's unseemly.
It's a nice suggestion, to live in the moment and be spontaneous, but it's highly impractical. Sometimes it makes sense to work with more information when it's available. Would you randomly select and just sit through a movie? A TV show? How about buying a random car? Selecting a spouse? Sometimes it makes sense to be discerning with limited resources. I'm as zen as the next guy, and live in the moment. I just got to this town, and I'd like to start my search with what people think are the most awesome places to eat. Is that so wrong?
It's surely not as wrong as you guys thinking I'm conducting my life improperly for wanting information about where cool places to eat are.
