Recently, after reading one of my posts, a new acquaintance wrote to me and said, "You must love words".
That got me thinking. 
 Yes, of course, I do love words. 
Our English language is ripe with interesting twists and turns and full of humour...humour laced with curious surprise.
I love to read words. 
I love to write words. 
But, most of all, I love to think about words. 
 That will probably surprise many people because I expect many people perceive me as more of a talker than a thinker. 
What's worse, most people probably perceive me as a complainer, possibly a rather pessimistic person. Naturally, I have a much kinder opinion of myself. I consider myself to be more of a thinker than, say, a constant complainer. That is not to say I do not express objections rather regularly. (so much for whatever that rule means about 'no double negatives')
I have learned to free up time to listen to most [but not all] people who complain. Usually, where there's smoke there's fire. And, where there's fire a spark is likely to be lurking nearby. And we all know sparks ignite. 
And sometimes sparks ignite change for the better.
I wouldn't want to be blind to those sparks.

Curiosity uncovers problems.
Complaints are, at their roots, statements of problems.
Problems are wonderful routes to opportunities.

It's attitude that counts most. 
Problems uncovered with a spirit of adventure are valuable enough to excuse the complaints that carry them.

Don't shoot the messenger until you've at least had a chance to see the opportunity.
