To Become Or Not To Become

Martin says I must become a psychiatrist precisely because I understand so much about how the enterprise really works - so I could help many people. This makes a lot of sense, but to me it's still not very convincing. It is a bit like recommending someone who understands everything about politics to go ahead and become a politician. A layman has the luxury to be optimistic; when you know the organization well enough, you may also know that it cannot be changed.
