IF 73-year-old Marjo de Waard could give her 15-year-old self a few words of wisdom it would be finish school and say no to sex, alcohol and drugs.
While Marjo has no regrets in life, if she was to do it all over again she would have finished her education and followed her dreams to become a teacher or skater, as well as staying pure until marriage.
Marjo left school when she was 15 and entered the workforce instead of studying at university after moving to Australia from Holland with her family.
"I worked in office management and managed boutiques," Marjo said.
Like a lot of us will admit later in life, the mother of two would tell her teenage self to listen to good advice from her parents and to budget your money.
Marjo married at a young age and said growing up with her children was a great adventure.
Pat Harvey said if she hadn't of listened to the good advice of her parents, getting out of one particular situation involving boys may have ended badly.
The 74-year-old snuck out to a dance when she was a teenager and took off with a bunch of older boys from church.
"Everyone was pashing, I had never had a kiss before so I started crying and they sent me home," she said.
Ann Baker, 79, would tell her teenage self to grow up and find out the difference between love and lust and contrary to to most, she said she wouldn't have always listened to her parents.
Betty Inwood, 88, said she wouldn't have any advice for her 15-year-old self and if she could do it all over again she would live her teenage years just the same.
"I grew up in a small country town in NSW and I loved every moment of it," Betty said.
Peter Old's from Old's Engineering in Maryborough said his advice to 15-year-olds of today would be to practice honesty and respect.
