I just don't believe in work/life balance. I'm sick of hearing about it. I'm fundamentally opposed to balance in every shape and form. I believe that nothing succeeds like excess. And that balance and moderation should be avoided at all costs.
I work 7 days per week. I also play 7 days per week. Working 7 days per week makes my life easier, fun, and more enjoyable. It takes the pressure off the 5 day work week by giving me valuable stolen hours of the weekend to lighten the ever growing load. I get more done in a 3-hour session on a Sunday morning than in 3 days of a normal working week. And I still have plenty of time to do all the other stuff I want to do with friends, family and alone.
Working 7 days per week is all about attitude. It is an attitude that says I'm determined to live my best life every day. The work I do at weekends is always work I want to do. It's valuable, rewarding and uplifting.
If your job isn't like that - change it.
