I believe you can be 100% productive and it's not about the amount of time you work. Since I started my own business and have complete control of my time, my productivity has sky-rocketed. I measure my productivity by making sure I get the to-do's on my list for that day done. I almost always get them done these days and in a much shorter amount of time. During a work day in the office, I found that I was constantly distracted and wasted so much time that often I wouldn't complete all of my tasks and left the day exhausted and deflated.
