Happiness is a daily decision, according to cartoonist and writer Andrew Matthews who spoke to 500 secondary students at Tang King Po School last week about how to be a happy teenager.
Matthews is touring Hong Kong to introduce his new book Happiness Now.
His other popular titles include Being a Happy Teen, which has sold over four million copies and has been chosen by Tang King Po School as a textbook for the students' reading activities.
Andrew Fung Ting-wa, the head of the school, said many teenagers lead a comfortable life and are well protected by their parents.
'They rarely have the opportunity to handle problems on their own, so when a problem - even if it is not a serious issue - comes up, they feel scared and will avoid it,' said Mr Fung.
Facing challenges was one of the main themes of Matthews' presentation, during which the writer drew lively cartoons on stage to illustrate his ideas.
