Come today, gone tomorrow

I have been sitting here at my desk staring at the computer for almost an hour already and still I'm at a lost at what to write. The funny thing is I had this interesting piece in my mind just last night and had planned to write it early this morning. So here I am at my desk as planned but I just can't remember what it was that I had wanted to write. Been unsuccessfully trying to recall what it was that got me all excited last night so much so that I had difficulty sleeping! I had to say to myself, sleep first. Tomorrow early in the morning you can write it. But now, its all gone! Just like that. The memory just fail. I give up!
