The fog
At the moment I have the luxury of not having to push myself too hard if I know I am not up to it for some reason. For example today, I was woken up early and am feeling foggy. I know that I am not going to be as effective in the way I work, and that any major decisions will be better made tomorrow.
I call this a luxury because I in working for myself I have the space to decide what I do each day. Today for me then is about slow and deliberate action.
Or perhaps I just need a cup of coffee.
