As for Twitter, I've found that you have to learn how to make it add value rather than subtract hours from one's day. Certainly, it affords narcissism and distraction.

By the time you get a job, you know how to behave in a meeting or how to write a simple memo.

It better to SUBTRACT what isn't needed than to ADD what isn't needed.

Mindfulness means being aware of how you're deploying your attention and making decisions about it, and not letting the tweet or the buzzing of your BlackBerry call your attention.

Attention is the fundamental instrument we use for learning, thinking, communicating, deciding, yet neither parents nor schools spend any time helping young people learn how to manage information streams and control the ways they deploy their attention.

People look at me, and I dress a little unusually and they think, 'Oh you must be from California.' Of course, people in California think, 'Oh you must be from from Mars,' so, you know, your next-door neighbour is not necessarily the person that you are going to make a connection with.
