Lo Ming, 21, a student of Wah Yan College, Hong Kong, was one of the guests.

He lost his father and mother when he was small.

And when he was young, he suffered from cancer.

A good part of his life was spent going from one hospital to another, receiving treatment for his disease.

But the young patient never gave up hope.

'When my mother died, I had to live on my own. I became hot- tempered because of the treatment for cancer.'

However, all the hardships he had suffered did not make him want to take his own life.

'What made me angry was to find so many young people committing suicide for minor reasons,' Ming said.

He really hoped youngsters would change their outlook, instead of grumbling.

Compared with poor people in developing countries, they should count their blessings, he said.

Cheung Yun-hang, 17, was another guest who was disfigured after the Pat Sin Leng blaze tragedy in 1996.

The music lover went back to school after nine months of treatment.

On the sharing night, he and his band performed for the audience. Yun-hang played the drums.

He lost the fingers on his left hand after the tragedy, which ruined his dream of becoming a guitarist. But optimistic Yung- hang soon mastered the drums because he loved music.

'It all depends on yourself. I chose not to submit to the tragedy but to fight for survival, ' he said.

Other guests included Commercial Radio DJs and singer Hacken Lee.

Amy Au Chi-ping and Lily Wong Sin-ling, both 15, of Holy Trinity College, had positive attitudes towards life.

Chi-ping said pressure mainly came from her studies because she was concerned about her marks. When she feels upset she tries to talk to her social worker.

'A full life means having physical as well as mental health. Therefore, I do a lot of exercise and volunteer work,' she said.

Sin-ling agreed with her. She said peers were important for growing youths.

She said she was lucky to have good friends who gave her support and taught her how to handle pressure in the right way.
