Another thing I've been doing to help me stay organized and proactive is to fight hard to focus on ONE task at a time.
I have the tendency to be reactive and start 8 things at once. I am slightly addicted to the idea that if I don't do it RIGHT NOW, then I will forget about it forever. To combat this, I have been bringing a pen and paper with me when I am completing a task and I will capture the "To Do" that pops into my mind. In the book Making Ideas Happen by Scott Belsky, he calls it the backburner.
It's incredible how much easier it is to make progress when you stay singularly focused one thing. The Big Picture vision is essential to have as you need to know what the end looks and feels like. But you also have to dissect the project into little manageable bits and pieces. Slowly chipping away is the hardest, but best way to get something done. There's no shortcut to success or completion…and if there is, then the task probably isn't worthwhile to take on in the first place.
