Work hard in your younger age. When your older age, even if you think you want to work hard, your health won't allow you to work hard. Work Hard, I mean in the sense like "what ever your health allows". Work hard and make the country to grow more. When you work hard, no one will think you are cheating anybody. But if you don't work after getting salary, then only, one feel bad feeling. 9-5 or M-F & when situation demands 8-6 M-F.
