Driven To Write

Like the title says, I'm driven to write--sort of. See, I'm always coming up with all sorts of great ideas when I'm driving. Story arcs, characters, comedy bits, songs, game concepts... When I'm driving, I usually find myself wanting to stop somewhere and write.
Which is hardly surprising, seeing as how driving consumes a considerable bit of my time these days. When I'm three hours in to a seven hour drive, I often feel desperate to stop, to write, to stretch, to do ANYTHING but drive.
And then I get to the hotel and I have oh, so many things to keep me busy... I have to check in, to unload my luggage, get settled into the room, use the bathroom, call my wife, set up my computer. And then I can write, right?
No. Usually I have to find the venue, check in early about the sound (I'm a guitar act. Sound is VERY important to me. Crappy sound can all but kill my show.) Then I'm hungry, and have been eating fast food all day. My wife insists (and rightfully so) that I should eat real food as much as possible. So I find a sit down restaraunt and order something other than a burger. And then I have to get back to the hotel and get ready for the show, then back to the venue and perform.
And then I can go back to my room and write, right?
Alas, no. Then it's merch sales and shmoozing, getting paid by the manager, and the load out, and calling my wife again to let her know how the show went. Then (if I've been drinking at all) I need to make sure I've waited a suitable amount of time before I drive back to the hotel, and by the time I do...

...I'm too tired to write. Often I'm too tired to sleep, too. So it's HBO or Showtime and movies I never wanted to see in the theatre until 3 or 4 am (I can't tell you how many times I've seen Madea's Family Reunion...) And then I sleep.
Whether I sleep late or not, I'm invariable not interested in writing when I wake up. I have to get around, sometimes in order to start the process all over again (including the driving.)
I'm driven to write, but when I have the drive, I never seem to have the time.
