I’m 15 years old. I made a decision to stop watching movies last Rosh Hashana, and boruch Hashem, I haven’t slipped once.
I’m telling you, it’s worth the leap. Last summer I said to myself, “There’s no way I’m not going to watch movies. It’s not going to happen.” It happened. Now I have much more time, I can concentrate better in learning and davening, and I’m just in general a happier person.
If you’re on the fence, and you’re scared to make a final decision, try it for two weeks. Just two weeks! After that, try another. Eventually, you’ll get used to it, and after a while,it will become a non-issue for you.
