Coming out of my cage and I was doin' just fine

For the past week, I have been driving to my parents' house to take care of their gardens. It has been many hours of picking raspberries and watering tomatoes. Yesterday, I was so hot and annoyed, I nearly lit the raspberry patch on fire. Instead, I went back today, my final day of duty, to pick just a few more. The end is near and I am happy to be done going over there for a while.

Except, I left my day planner there.

I am a moderate planner user. I don't plan my day by the second, but if you want me to be somewhere at a specific time, you best tell me when I have my planner at hand. I can remember most of what is in there right now (and have started a contingency planner), but I'm hurting for my list of phone numbers. I also left my notebook there, in which I write my lists, my ideas, and my plans. Yes, I could drive over there. However, with the gas prices as they are, I am making do.

What is the lesson here? I should use my PDA for more than just Jawbreaker.
