Consider the following…
40% of our worries never happen. Anxiety is the result of a tired mind.
30% of our worries concerns past decisions which cannot be changed
12% of our worries centers on criticism by others, meant to make us feel inferior
10% is related to health, which only worsens as we worry
8% of our worries are legitimate, showing that life does have real problems which can be met head on when I eliminate senseless worry.
