I got a disposable. Got lucky and liked the flavor - better than a cigarette.
Decided "hey, this is kinda good - and it's way healthier".
So I invested in better gear - Not disposable.
Quit smoking, and wasn't even trying to.
Then over the next couple years, I went from cig-sized, to Ego type vapes, to tanks, and ultimately to squonkers.
But if there's a secret, my opinion is that it might be "Flavor" and "Draw" - you kind of should plan to keep trying different things until you find one that satisfies: the "puff" (draw, airflow, etc) and the flavor.
