I am of the belief that true politicians are of a different kind of breeds. They live for a cause and are willing to make huge sacrifices for the cause. People like LKY could have made big bucks as a lawyer in the private sector, but he chose the path less travelled. Dr Chee could have lived a very comfortable life with his family in Australia, Europe or States , working as a teaching professor in some university, but he chose to pursue the cause he believed in , just like LKY. No sacrifice is too big for Dr Chee because to him, that is what makes his life worth living.
