I just go out in the morning with the intention of returning with some money. I have found that if I clean their windows people are much more inclined to give me their money, but I'm not a window cleaner, oh no!. I see my job as collecting in the money, the window cleaning is just an inconvenient task I have to perform first.
My old dad used to say "If you want to find the easiest way of doing a job, give it to the lazyest bloke"
which is basically why when WFP came along I saw the advantages of it.
I'm still working on trying to find a way of collecting the money without cleaning the windows but its proving difficult. Until I do its WFP for me
