My Mother used to say this all the time. I don’t remember her saying it to me, but I remember her saying it to my kids and their cousins. Her theory has always been that there are too many interesting things to do in life, and one never, ever needs to be bored. If you are bored, you’re just not being observant enough of your opportunities.
Of course, when you’re a kid, being bored usually means that the entertainments you’re looking for aren’t readily available. For me it meant there was nothing good on television. (Back in the day, you couldn’t pop in a DVD, pull up NetFlix online or watch YouTube. You had to wait for the program to be broadcast. And if you missed it, you missed it.)
Now, I guess, a kid is bored when the WiFi is out.
