This is a list of bad ideas.

1. Not turning off a cell phone, even when you think it can't possibly ring. This is a guarantee that it will ring and cause strife.
2. Parking a car on an inclined sheet of ice. This will guarantee that your car will be immobilized. Again, strife.
3. Modernist planning. No one wants to live in a concept.

Let us all take a lesson from this.
