Personally, I've never been a fan of those overly rigid project planners.  It always feels too complicated.  What works for me is a simple "to do" list - just an ordinary piece of paper divided into 3 sections - A-B-C if you like or "now," "soon" and "later."

What I've learned is that what can sometimes keep me from getting things done is that I start too often with the "C" priorities instead of the "A" priorities.  So it can take some discipline here. But the simple act of writing it all down means I don't have to remember everything and that alone makes it feel more manageable.  I refer to my list each morning and keep it handy throughout the day in case anything else needs to be added  and so I can check things off as they are completed.  Don't worry if things linger on the list for days - what I've found is that sometimes waiting a bit can turn something that seemed urgent into a "nice to do" not a "must do."

We've got a great article on the site you might also enjoy checking out "Printable To Do Lists for Organizing: Tips for Creating your own To Do Lists" and you can find it in the Organomics Resource Center section of the website.  We're also working on some templates and we hope to post those soon on the site as well as your challenge is one shared by lots of people
