Giving of oneself is priceless.

  
I feel that there is genuine value in giving time to voluntary causes, especially when I consider how regularly I am stopped on the streets of London and asked to donate money to charity. 

Giving an hour of my time, I feel, is of more value than giving the equivalent of my hourly wage… and if I am honest I consider an hour of my ‘free’ time to be worth more than I charge my employer.
