Why don't I want to do anything?

I am do stuff when I have to, but if I could just do nothing all day, I would do so. in fact, I'm working really hard to start up a good website that will make me more than 6 figs so I will have to work much less after it's done. the truth is, I don't care about people, I don't care about making the world a better place, I don't care about what anyone thinks of me, and I don't care about accomplishing anything. All I care about is pleasure (now they might be more complex pleasures like going to the opera or enjoying a fine tea or wine, but they're still pleasures). I just want a fun, easy life, nothing more, nothing less. is there something wrong with me or am I just at a bad place in my life?
