"I'm always trying to instil confidence in them because no matter what we always face bumps in the road, don't we? And there are these hang-ups and anxieties," explained Penny.

"At the end of the day, if you can just be true to yourself and try and exert that confidence with a smile on your face it can help you get through things."

What better charity than The Prince's Trust to really show that in its full glory, looking after young people because they are the future after all? It's giving those children and young people who haven't had the best start in life a second chance."
