This year, our regular columnist Kishore Mahbubani has devoted his monthly columns in The Straits Times to new Big Ideas which will help Singapore succeed in the next 50 years.

His first Big Idea is for the country to have fewer cars. The second Big Idea is to make our public transportation No.1 in the world. The third one is to strengthen the Singapore spirit. Read The Straits Times this Saturday to find out his fourth Big Idea.

Professor Mahbubani, who heads the Lee Kuan Yew School of Public Policy, has been hailed by British current affairs magazine Prospect as one of this year's top 50 world thinkers.
