the state of New Jersey workshop

I was invited to be a leader in a as everyone knows the "fortune" 100 strong companies, in the state of New Jersey workshop. Facing the new crop intern all-day events. At one point in my lecture, I talked about the reason we took no action is in many aspects. Many excuses, we create a delay or postpone our success.
I talked about how we have a bad habit of "rationalization" why some things cannot be done or completed. We delay, because we convince ourselves, thought: it can not be completed, I don't have enough time, I have too much has been done, I'm short of money, now is not a good time, ill my dog I am not now any mood, I am not clever enough, I have no,,, and so on, qualification... Etc., etc.. Thoughts of you! We rationalize, why can not we go.
Have you thought about breaking up the word "rationalization"? In his ability to 'rations. This is what we do, we come up with excuses, why can't we do something, or why what needs to be accomplished, we haven't started. We feed their lie small daily doses of their own situation, we convince ourselves not to take action.
Later the leadership in the workshop, a student asked a question, how to network to his current focus area outside of work. I answer, ask him what is to stop some of his disorder. He answered a series of why he can't do this excuse (office is not in the same building, it is difficult to get the holder, which is a big company, etc.). However, every excuse, I do not hesitate to point out his, just, an excuse. These inconveniences, rather than a hindrance. Great differences!
Then, I doubt his commitment (i.e. how bad, he wants it to change). He stared at me the way, that he got a point. You can see his excuse, no network and his team are effective. He was "reasonable" why didn't he do that.
