A useless twitch for a writer

I want to say the things you want
I want to do the things you'd like
I want to love the things you love

But when you want the things you crave
You'll dig yourself
An easy grave
Where your personality will lay to rest
Took over by thumps inside your chest
A cavity that's not worth eating
You search for the secret meaning
In the want
In the tire
Running on your own desire
Of things you cannot have or need
Oh, What an ugly, disgusting deed.
