"I entered politics because I saw it as a continuation of public service. And I have over the years found my calling in public service. It was not the case when I started out to work, to be fair. When I started working, I was an economist in the Ministry of Trade and Industry. I had been rejected by the Public Service Commission to be in the Administrative Service, so I was not involved in a lot of policy work. My work was largely around economic analysis. I would be the quant, so to speak, or the guy doing all the analytical work; somebody has an issue, you want to analyse what happened to the economy, under these circumstances, there is a regional financial crisis, what is going to happen to Singapore? Well, you ask me the question, I will run my models, I will do the technical number crunching and I will give you the output. That was a lot of the work that I was involved in at the start of my career."
