If you are asking people to donate their money, you have to be doing something which challenges you or pushes you outside your comfort zone.
This week we've seen Bay residents shave their hair off to raise money and awareness for Leukemia and Blood Cancer New Zealand.
That's something I can get behind, particularly when a girl volunteers to lose their long locks.
This week 17-year-old Otumoetai College student Mackenzie Latif had her hair shaved off for the cause.
That takes guts.
I'm not brave enough to do that now, let alone during my high school years.
Yes, hair grows back but it takes a wee while to grow back the long shoulder length locks so many teenagers pride themselves on.
Mackenzie's friends and family obviously agreed her decision was one that deserved their support - she managed to raise more than $1000.
While it's more socially acceptable for boys to have no hair, I was equally impressed by 9-year-old Oscar Maybury who shaved his head for the second year running after deciding he wanted to do something to support people battling blood cancer.
It's great to see a young boy thinking of others.
We could all learn a thing or two from Mackenzie and Oscar.
