fretting long enough

[unpakwon]

Would you please paraphrase the following in red more easily?

You and I could probably eliminate nine tenths of our worries right now if we would cease our fretting long enough to discover whether, by the law of averages, there was any real justification for our worries.

Thank you.

If we could stop worrying long enough to actually investigate the issue and see how likely this is to happen, we could probably eliminate most of our worries altogther.

In other words - we are so paralyzed by the fear of what might happen that we can't take any action to see whether it's like to actually happen.
