When working on a project, if you put away a tool that you’re certain you’re finished with, you will need it instantly.
Nothing minor ever happens to a car.
Any tool dropped while repairing an automobile will roll beneath the vehicle to its exact center.
When anything is used to its full potential, it will break.
Anything hit with a big enough hammer will fall apart.
You will need three umbrellas: one to leave at the office, one to leave at home, and one to leave on the train.
