Alright, so I'm starting to lose interest in doing things I used to enjoy. For example, I bought a meet&greet ticket for a Napalm Death concert that's going to take place at the end of the month. I still love listening to the band but I don't feel that desire of going to the show, even though I paid a lot of money on the ticket.
Another example would be there's a woman I'm deeply in love with and I want to marry - she doesn't know me, she's kind of a public person, anyway, it's not what this post is about. The thing is, I began working out a lot more, reading more books than before (I would even finish a book in a few others), taking better care of myself, etc. Now, I still want to do those things, I still want to go and find her, but I don't feel like improving myself anymore, though I want to. And it's not like I'm lazy, it's just that I'm having a 'screw it, it'll work anyway' attitude, in two words: losing interest. What should I do? Is it something to worry about?
