Think Globally to me is to be flexible. If this country's laws don't allow you to do something but can do other things, then do other things.
Act Singaporean

Promote Singlish. Promote kiasuism. Promote kiasism. Promote multi-cultural, multi-religions, multi-racial tolerance.
Edit: forgotten to sustain with facts
For think globally, I can't think of anythign as of now.
Act Singaporean, to do things in our way, our own style. Like what happened in CES (Consumer Electronics Show). Creative won an award.
This is what I think. No sure if it is correct though.
