Witnesses Types Which Get Me Moving
First: Little children. If there are children around me, even imaginary ones, I find it awfully difficult to slack. It seems like a bad idea to communicate dullness to children who may start thinking it's normal.
Second: People who trust me the most. Probably because trust takes time to build. And probably also because one realizes it's painful to have your trust broken.
Third: Everyone. This is more colloquial than tangible. But not hiding from anybody seems the ultimate card in trying to get myself off my ass.
It seems this audience can also exist in one's imagination. Imagination might be powerful enough. But reality does remain unreplaceable, and not to mention, independent of oneself.
