I'm an extremely absent minded, so I rely on routine. When I come home from a shoot, I take out my card and pop it in my computer. I leave my camera by my computer as a reminder that the card is not in it. Once I've dumped my pics, I put the card back in the camera and format it. Then I set my computer on top of the dresser I store it in and charge the battery nearby. Once the battery is charged, I put the camera in it's home with the battery in it.
