In a previous post I talked about using time. It is a topic I think about a lot because it often feels in short supply. I know a good part of this is my own doing. I value a lot of things that require solid blocks of time.
It takes time to eat well. It takes time to get enough sleep. It takes time to exercise (when I do). It takes time to take time to build and deepen relationships with people I want to be to be close to. It takes time to achieve excellence.
When it comes to the workplace and email, Merlin Mann had some great insights and thoughts in his recent talk about time and attention. If you are a knowledge worker or work in a culture that is highly dependent on email, I highly recommend listening to it.
