I was laying in bed at about 4:00 this morning and an idea came to me. It was an idea about how to solve a hard technical problem. I love that. It might be the best part about being an engineer. The idea, if implemented well, might solve the problem. It might not; the problem is hard. Still it will be very interesting, even fun to try it out. I was invigorated enough by the idea that I got out of bed and went in to work to try it out. It will take me several days to do it, but before now, I did not even have a plan. It was like I was an author with writer’s block. At any rate, now I have something to try and it makes me happy.
