"Supposing I'm now 21, 22, what would I do? I would not be absorbed in wanting to change life in Singapore. I'm not responsible for Singapore...Why should I go and undertake this job and spend my whole life pushing this for a lot of people for whom nothing is good enough? I will have a fall-back position, which many are doing - have a house in Perth or Vancouver or Sydney, or an apartment in London, in case I need some place suddenly, and think about whether I go on to America."
