Do not spoil what you have by desiring what you have not; remember that what you now have was once among the things you only hoped for.
Epicurus – Greek philosopher

Restarting Excel and Windows

Even now sometimes a full restart is a possible solution.

I recently had a macro returning a weird error message about an action taking too long. Restarting Excel did not fix it.

So, I restarted Windows and the macro worked as expected.

These days with so many apps running in the background, sometimes the only solution is a restart of Excel and Windows.

Turning it off and turning it on can still solve issues.
