Where is time going??

Got a new diary for Christmas. Trying to view use it for everything and I'm finding I have very little time to do nothing.

I wonder if this is normal? Is this what being a grown up is like??? I guess if we ever have children I went be able to do all these meetings and gatherings? I just don't know how some people do it.
I cancelled my meeting today because I just felt like I might over do it. Still feeling guilty however I got so many other things done instead.
