Worry

It's often said that worry serves no useful purpose, and that may be so,
but it's really hard not to worry. Life is filled with unknowns, and what ifs....

Circumstances in life often require consideration and much thought, so,
a little worry may be in order to sort out the issues, and look at the pros
and cons of the forks in the road we run across.

So, the trick really is how to worry constructively, in proper moderation,
so as to make the most of it, and in the end to be happy.
