I like the number "3" in my daily life. It's the trifecta of awesomeness, not too much and not too little. So, I create a short list each day to work on the core tasks in my business.
I'm all about bridging efficiency into my life, and setting realistic expectations for myself that are achievable. I want to leave my business days proud of the job I accomplished, and sometimes just saying I can shut down the computer when I finish my tasks and play outside is a worthwhile investment.
