I personally don’t enjoy partying. Because, I don’t find any meaning in it. Of course, you shouldn’t find any meaning in a party. But, hope you understood what I mean. Giving just a company to others I don’t have any problem with that. You get to know new people too.
But too much drinking and smoking is not something I prefer.
Ofcourse, thinking of work everytime is also not a good idea. You need leisure time too. So that you can refresh yourself and work more. Balance is necessary.
