Shortly after children learn to talk, they start asking Why.
Why is the sky blue? Why does that man have funny hair? Why do I have to go to bed? Why can’t I have a kitten?
They’re certainly not rhetorical questions. When a child asks something, they expect answers with all the fervency of an determined interrogator.
Why? Well it’s what children do. It’s how they learn. It’s the way in which they make sense of the world around them (we hope).
Unfortunately like a lot of the stuff that came naturally to us as kids, we can be inclined to stop asking questions. Perhaps we feel our learning days are behind us, especially if our memories of school days are less than rosy.
But equating learning solely with school is almost certainly unhelpful. We didn’t, for instance, need the structure of teachers and classes in order to learn before we were old enough to start school, did we?
In much the same way, we have the wherewithal to keep learning long after we’ve hung up our school uniforms, and acquiring knowledge (sometimes simply for its own sake) is a fine contributor to maintaining a positive mindset.
When your mood is low it can be hard not to ruminate, turning problems over and over in your mind. But when your curiosity gets the better of you, causing you to hunt out answers to whatever’s bugging you, you’ll be inclined to forget your worries, if only for a while.
So why is the sky blue? Try Google. It has 302 million results for that particular question.
