... is so very hard to do.
When I was younger (way, way younger), I was probably like you when YOU were way, way younger. We didn't want to go to bed early, primarily because we weren't sleepy.
And then, we didn't want to wake up in the morning because we were still sleepy and "needed" a few more minutes, or a couple of hours, of additional shut-eye.
Hence the conundrum of younger days: Why did we have to go to sleep when we weren't sleepy, and wake up when we were? No good answer to that one.
But now I'm older, and my problem is that I fall asleep too early, and wake up too early. Waking up is a pain, but not falling back to sleep is even worse.
I never used to be able to nap, try as I might. These days, however, an afternoon nap isn't so hard. The body cells and droopy eyes demand it, actually, so I just give in.
Waking up is so very hard to do.
