NOT-to do list

I've noticed people like to make 'to-do' list, but for an everyday basis wouldn't it be just as safe to have a NOT-to do list. You know, things that you could run across that would just fuck your day up, in turn just ruining your priorities on your TO-do list.
Here are a quick few I've wrote for tomorrow:

What NOT to do on Thursday:
1. Wear shorts and flip-flops while its raining.
2. Fall Asleep at work.
2. Trip in front of a bus...full of hot cheerleaders who will surely judge you for your clumsiness.
3. Run across a rattlesnake on your way to class/work.
4. Fart during class.
5. Fart during class while giving a presentation.
6. Take for granted Number 3 and 4 of your NOT-to do list.
7. Make a TO-do list.
