The problem with photography is that it is so easy, and yet so hard.  But this is also why it interests me.  I just wish I had more time to work on it.  Fortunately, I usually can find time during a trip - even a business trip - to pull out the camera.  I also seem to have the camera with me on travel more than I do on regular work days.  And professional photographers always say that you have to have the camera handy to get the picture!
