Some days I feel flat and completely unproductive. It's a struggle to get anything done. I find that time-boxing helps. Today I found that going for a run really helped. This morning I felt totally discombobulated. This afternoon after the run, I had a lot more focus. I still need to ensure that I get the right things done though.
Sometimes I think the best way to get things done is just to allocate space in the day in order to achieve them. For example; I find it hard to write blog posts. Left to my own devices, my blog would resemble a desolate wasteland. But all I need to do is allocate 10 minutes out of my day in order to write something, and I can get something written that I can upload to my blog.
This is the beauty of time-boxing, of the Pomodoro technique: It forces you to allocate a fixed section of time in which to achieve something. If you just make a space in time it's amazing what you can do.
I have created the following bit of Emacs Lisp that generates my daily productivity graph and displays it in it's very own emacs buffer. You can kill the buffer by pressing the 'q' key.
