I got all my big ideas "stolen", but not because I talked about them or told them to anyone, they were stolen because I didn't do anything with them, and waited till I have the best design, best business plan, best team, till my kids grow up, till I save enough money, what not. Someone else thought about it too, and simply went on and did something about it.
