I get so obsessed I burn myself out

How do I like not do this?🫤 I usually get so obsessed with something I think about it from when I wake up then when I go to sleep and I’m usually go to sleep watching a video on it. I’m thinking about only giving myself 2 hours a day to whatever I am obsessed with at the time so I don’t ruin it. But how can I get that spark I did again before I burned out and how do I prevent it?
