What does that mean?

It means rather than dwelling on the hole, meaning the negative, the sadness, the crisis part of it.

Look at the donut.

And instead of utilizing all your time to think about, what was and how terrible it is and you must have been wronged or it was just a disaster.

Think about what comes next.

What lies ahead in your future? And focus on the donut, the positives.

Keep your focus.

In most cases.
