1. Maslow: Finding New Ways to Tackle Problems

"I suppose it is tempting, if the only tool you have is a hammer, to treat everything as if it were a nail."

This famous quote from Abraham Maslow is often known as the law of instrument or Maslow's hammer. Essentially, it suggests an over-reliance on a familiar or favorite tool. While such tools can sometimes be helpful, they can lead to approaching problems in ways that are not helpful or even destructive.

In psychological terms, this might involve always relying on the same coping mechanisms, rather than looking for new solutions.
