What do you do with your weekend? What can you do? Is there anything you need done during the week that you find yourself thinking, "If only I had time to do XYZ, that would help so much!" Then take advantage of the weekend! Use it to dedicate 2-4 hrs towards those things you couldn't do during the week.  If you're burnt out every Monday, then maybe you need the weekend to chill back and breathe a bit, relax.  Everyone has different needs and is on different levels of the playing field, find out whats best for you and your business.
