Mr Tharman, who is among the presidential hopefuls for the upcoming election, was speaking as the guest-of-honour at The Halogen Ball, a fundraising gala dinner organised by Halogen, a charity focused on empowering young people.
The dinner also marked the charity’s 20th anniversary.
Not everyone has to be the loudest voice in the crowd, or the leader of a movement, said Mr Tharman, 66.
Young people can make a difference by mentoring children, volunteering at a social service agency, or simply lending a helping hand where needed.
