How often I have found that we grow to maturity not by doing what we like but by doing what we should. How true it is that not every 'should' is a compulsion and not every 'like' is a high morality and true freedom.
I thought my life was mapped out. Research living in the forest teaching and writing. But in '86 I went to a conference and realised the chimpanzees were disappearing. I had worldwide recognition and a gift of communication. I had to use them.
