Birds are the worst. More specifically, birds that sit outside my window at 6AM every day and chirp relentlessly- those birds are the worst. I have no problem with the rest of the bird population. They are cool with me. My dog's problem with them is his own. Unfortunately, my dog and I seem to have opposite issues. He ignores the one bird I hate, and relentlessly attacks the rest of them.
The bird messed with my sleep. Why is that such a problem? Because it's made writing the blog + article + speech that I had blocked out on the morning calendar nearly impossible.
Sleep gives us energy. A lack of sleep takes it. And energy is one of the central factors in our capacity to focus on the right things at the right time. (thinking about that damn bird is not the right thing right now).
If you want to be great at your job, i look at your sleep habits (and the birds). Nothing will rob you of your capacity for quality work quicker than poor sleep. And nothing will shorten a blog faster than a bird at my window at 6am.
