When you have family, work, friends and some other activities, one way or another you will plan them all. This does not mean that you have some kind of addiction. In fact, this question is relevant only for a small number of people (who have an almost unlimited amount of free time), most people live in a tight schedule and a constant lack of time.
Correct.
Managing your time doesn't mean you're addicted on it, in fact you're very far from it because gambling addicts always prioritize gambling above all else, instead of being productive, they will just spend most of their time on gambling throwing away their money every single day, that's the real addiction. Time management is always important to boost yourself on doing the things you need to do to feed yourself or your family every day.
Sure. By the way, maybe this is why gambling addiction (like any other) has a certain appeal - they seem to erase all other worries of a person and he has only one goal - to gamble, gamble and gamble. This is a pretty strong drug and it is not surprising that in order to quit it you have to switch to another addiction or religion or something else dubious.
