I want to party all the time lately.
Why do you want to party all the time?
I just don't care about anything else.
I get that you want to have fun, that's totally normal.  However, you shouldn't spend all your time playing. You need to balance it with more productive things as well.
But I don't want to be productive.
I get that it's more fun to party then to do something productive, but you should really try to do other things as well. It's not good to spend all your time having fun. There should be a balance of work and play.
