He said, look at your outbox and see how many mails that you sent out were the replies to incoming mails and how many were self initiatied emails. This could give you an indications of how time do you send in "reaction" as to "action".
Ofcourse this does not apply to everyone, but still i found this simple analysis very powerful.
So many times we just end up in life just waiting for something to happen and reacting and not acting. How many times we wait for some other person to start conversation, go over to adjacent cube to start talking instead of letting time go, in a gathering waiting to be forced to come forward to share the experience rather than volunteering, waiting for life to happen instead of making it happen.
Now whenever I reply to email, I have become little concious, wondering if I could have initiated that or should I start some similar conversation with some other person.
