You catch more flies with honey than vinegar. It works with people too, but that much honey can get expensive so I choose to ignore them instead. What would I want with a crowd of people trapped in honey anyway? I have enough trouble with just one of them in a face to face conversation.
A bird in hand is worth two in the bush. Unless, of course, the bird in hand is dead: in which case your bird isn't worth squat and there are two perfectly good birds in a bush laughing at you.
