Too Tired To Write

I almost always feel too tired to write. When I'm not tired, most times, I am on my way somewhere (like work) or just kind of don't feel like writing. When I am out and about on my days off, things come to mind that I could write about, but I am not by the computer so by the time I get home, I have either forgotten what I thought of writing about, or I don't feel like it anymore. I do like to write, but...it's just like watching a show like Jeopardy. I like facts, and find them facinating (and might even try answering the questions myself), but it is almost like pulling teeth to make me actually watch it. I don't know why. "Steeerange".
