Do you have a 'picker' and how well does it work ?

Mine is shit and might as well not exist.

That's picker not pecker but for all intents and purposes that's shit too. ;-)

How well does your 'picker' work? Does it lead you to positive or negative romantic/intimate/relationship outcomes?

How do you 'train/teach' your 'picker' to make better choices (or just to make choices at all)?
