"I don't know about investment. I have a cousin who helped me [when I] bought some bonds and I let him take care of my money in the bank," Peter says.
Last Thursday, Peter was in Hong Kong on a concert tour - combining music and conversation - at Hong Kong Design Institute. More than 1,000 teachers and students from the institute and Hong Kong Institute of Vocational Education attended the event.
Peter has published a book, called Life is What You Make it, all about finding fulfilment in life. He uses his music to encourage people to search for meaning in life. He sings songs about social issues and the environment, and hopes to raise people's awareness about such issues.
"I think the value of the world is unbalanced," he says. "The world tends to measure success by money and gaining more money, but success can have many definitions. You can be a straight-A student and considered successful, or be successful simply being a happy person. For me, success is that I wake up feeling excited about the day."
His passion for music led him to give up his studies at university to pursue a career as a composer and musician. Peter says it is one of the best decisions he ever made, and his father fully supported him.
"My father is a man who enjoys what he does. He is 81; he still lives in the same house, drives to work and comes home and is sitting on the same chair and eating the same food. My father and I are doing the same thing in the sense that we are both doing what we enjoy doing."
His father advised him to follow his dreams, Peter says. "My father told me, 'Go for what you're passionate about. If your passion is collecting garbage, go for it'."
Peter was asked many questions from the audience about his father, but he says this doesn't bother him. His father's fame has helped him achieve his ambition of trying to make a difference in the world through his music.
"If I was in my 20s, I would probably be frustrated by people asking about my father," Peter says. "But at this stage of my life, I've been on my own and lived the life I've wanted. And without my father, I don't think I'd draw as much attention as I do, to inspire people."
