When you have to shoot, shoot. Don't talk

Sometimes there is a need to take a stand. There is a need to decide, one way or the other. The time to gather data is over. You don't know what you don't know. There is no point thinking about what you could have done to be more informed, to be more aware of the implications. Its like... doing the right thing at the intersection and not slowing down/stopping the traffic behind you. Whether the road taken will be the right one - will be known shortly. 

In cricket, a captain might decide to use a bowler at a particular time. In business it might be a decision of buying v/s building... sometimes it pays off, and sometimes it doesn't. Of course, there is a factor of 'instinct' involved on top of the data (all great leaders claim to have a good one), but wondering what you could have done, when you need to 'go' - can only harm the outcome

Once you have done whatever you could to acquire knowledge, go with conviction based on what you know. I am reminded of a line from one of the greatest western movies ever made - "When you have to shoot, shoot. Don't talk". That scene and this quote pretty much sums up what I am talking about.
