Working brahs
Work hard/smart/easy/whatever. Just don't forget that every hour you work is one less that you have to yourself in a short and once-only life. The realisation of how important this is may not come until it's too late. This is where it can be important to enjoy your work, too.
Personally, I think the three day weekend is where it's at. I was never happier than when I worked a 4 day job. Had plenty of cash to get by and not only was it one less day a week of work, but one more day a week of time to myself. Unfortunately the world isn't set up that way and most jobs are designed to suck 5 days of life from you in a 7 day week
But...some of the happiest people in the world are unemployed or work very little; go figure!
