Still not a lie if you intended to do them. It turns out to be misleading, false and a failure but thats not lying.
Lying to yourself is still lying.
Also, saying you can fly is a lie even if you intend to fly. Saying you will lift a car is a lie even if you want to lift the car.
Saying you will do something and then making no effort to do that thing is lying. I don’t care that in the moment you say it you intend to do it, if you don’t intend to take the steps that lead you to do it, it’s lying.
Saying you will do the dishes and then never walking up to the sink or turning on the water and instead playing video games and then going to bed is lying. You will not do the dishes, even though you said you would.
