In the Christmas Special episode ("Party Games") of my favorite British political comedy, "Yes, Minister", Sir Arnold, the cabinet secretary, remarks to Sir Humphrey Appleby that "today's opposition is tomorrow's government".
A word of wisdom.
Because human hearts are weak, there is a tendency to take the status quo for granted. But history tells us that what appear to be the opposition today is acually tomorrow's standard and establishment.
The question is, with which you identify yourself today, the opposition or the government. I am one who always thinks that it is more fun to identify with the opposition, not only in politics but in scientific and cultural domains as well.
