The beauty of being an entrepreneur is that you are the CEO, the boss. You can set your own hours, work when you want and when you don't want to work. You can work 70 hours a week, or seven. Everyone today is busy, but you can be busy, and not doing the right things to be productive.
We need to plan our day, our week, our life. There's the dog to walk, laundry, errands to run, the taxes to file. We can bee-bop here and there, and never work...or we can work ourselves to death, and all for what?
It's your call about the weekends. Sometimes I have a big list of to-do's and I work for hours, loving my work. Other times, I take a break. I enjoy coffee on my porch, go eat nacho's (or carrots), shop at Target, or ride on a motorcycle!
Be aware of your sleep needs, the food you're eating, the weather, your body's stress signals. These things affect us as entrepreneurs. It's your business. Give yourself permission to succeed...or to be kind to yourself and sleep, eat chocolate, and go to a movie.
If you want to work on some projects on weekends, do it. Or if you need some R & R to refill to do what God's called you to do, then listen to your body. Whatever you do, though, love it and enjoy it!
