I developed a similar system to this last year, but instead of defining my tasks for the week, I'd just choose the three most important tasks I wanted to get done for the day at the beginning of each morning.<p>If I got my three tasks done, it was a productive day and anything else I did was gravy. If I didn't, I forced myself to look back at what I spent my time on that day. The three-task system helped me get focused to avoid "fake work" like meetings, emails, etc.<p>I eventually coded it up into a simple tool for myself that I still use every day. I haven't focused on marketing so I'm honestly the only user, but I'd love if the folks here could check it out and tell me what you think - <a href="http://three.do" rel="nofollow">http://three.do</a>
