You're looking at it: a $14 wire-bound notebook from Staples. And thank heaven, my 2009 edition just arrived today. (It's my fault for procrastinating. I've limped along the past 13 days with free calendar pages I printed from the interwebs.)
I used to use the Franklin system, on which you could spend hundreds for a binder and another $40 for new pages each year. And although I still like to go to the mall store and fondle the buttery leather binders, I just couldn't justify the expense anymore. Probably nobody else can, either, because they have been seriously dropping their prices.
This cheap-o planner works just fine for me. I write my occasional appointments on the left side of the page and my to-do list on the right side. I use the "notes" lines at the bottom to record the hours I can charge against book projects, and then later I enter them into our Bookmaster system, where the costs are amortized over three years. (Don't get me started on what a painful transition it continues to be from our old publishing-management system to this one.)
Now, the elephant in this particular room is why am I not using some sort of electronic system to manage my time? I think the answer is pure stubbornness. I like being able to pick up a pen and check off tasks as I do them. My little book is portable and doesn't need batteries or wi-fi. It's kind of the same argument we use when we say traditional books aren't going away. It's a tactile experience that I am loathe to give up just yet. Besides, if I don't keep using a pen occasionally, I will forget how!
What time-management system do you use? Why do you like it?
