So much more than so-so

I'm...    
ordinary      
just so-so      
not really pretty      
maybe not so lean      
but I dream      
to be so much more      
than mediocre      
living in a state of grace      
knowing I'll never hold the pace      
so I tell myself      
I'm a starlet incognito      
it's only water weight      
and who likes math anyway      
oh, but I'm so edgy      
thinking about shackles      
and whips      
practicing by myself      
I'm a pretend dominatrix      
with a bag full of tricks      
maybe I'm a pretend person      
except I have a dog      
all my dreams are in her eyes      
so I'm so much more than just so-so      
even if I'm incognito
