The law of harvest is to reap more than you sow. Sow an act, and you reap a habit. Sow a habit and you reap a character. Sow a character and you reap a destiny.
I have never described the time I was in Doctor Who as anything except a kind of ecstatic success, but all the rest has been rather a muddle and a disappointment. Compared to Doctor Who, it has been an outrageous failure really - it's so boring.
