System administrators in general are smart people. You're smart. I'm smart. We're all smart. We've achieved our stature through brainpower, not brawn. Sure, our good looks help, but deep down ours is a "brain" job. On average, people have a short-term memory capacity of seven items, plus or minus two. What about the average reader of this book? I bet you're closer to eight, nine, or, heck, you in the back row reading the comic book might be as high as ten (plus or minus three).
Turning to my personal to do list, I see about 20 items. Damn. That's a lot more than 10.
There's no way I can trust my brain to remember 20 items. I need a little external storage. So do you.
I hope you aren't insulted when I say "Don't trust your brain."
I don't trust mine. That's why I write down every request, every time. Whether I use a PDA or PAA, when someone asks me to do something, I write it down. This has become the mantra:
Write down every request, every time.
My brain feels a little insulted by this lack of trust. When someone asks me to do something my brain starts yelling, "I'll remember it! Put down that PDA, Tom! Trust me this time!" However, all the inspiration I need to record the request is to hark back to those times when I've had to face a customer who was upset that I hadn't completed his request and deliver the rather lame excuse, "I forgot."
In Chapter 2, I discussed delegate, record, or do. When we delegate a task, we don't have to record it, though it is sometimes wise to record that we should follow up with the delegate to make sure the request was accomplished. (We are, so to speak, our brother's keeper.)
Also, if we are going to do the task, we don't have to write it down. If someone asks, "Please pass the salt," I don't write in my to do list, "pass the salt," and then cross it off my to do list. That would be silly. However, if someone asks me to do something and I say, "Sure, right after I'm finished with this," then I write it down. Don't confuse "when I'm finished" with doing something right away. In fact, for me, the biggest temptation to not write something down is when I think I'll remember it because it's what I'm going to be doing next.
