when no words come

I keep sitting down at my computer, fingers resting lightly on the keys, with the desire to write something coursing through my being. Something meaningful, that I'll look back and say "Yeah, I wrote that. You should read this." Something I'll refer back to. Something that will provoke thought and action in the persons who read or hear the words.

But every time I try, every time I want to, it seems like there just aren't the right words.
Even though my mind is brimming with words most of the time. Even though I have notebooks filled with words no one ever reads, and probably even never will.

It never seems like there are the right words.

So what am I to do? When I wish that there were pictures and words for me to share, but there isn't?

I suppose most of the time I just give up. Don't press it, don't make an effort to try.

But what could I accomplish, what could I create, if I did? If I made an effort and took the time?
