What do you guys do when you lose interest 🤔

Edit: Of course I mean in physics, guys, for God sake 😂😂 the question has nothing to do with relationships 🤣🤣

Edit2 : Let me put this in other words; since people on reddit need details always: When I started physics at first I was so ambitious and excited about studying and getting good in it by doing lots of problems.. but now I feel ((slightly)) losing interest in it, or in another phrase: bored. I know it's easy to fix that. I fix it with solving tougher problems or reading pop science books or introducing myself to a new topic in another field in physics.

Just wanted to know what do YOU, guys, do to fix this?
