Some years ago, when I used to have lots of one to one meetings with people I met at networking events, I arranged to have such a get together with an accountant.
As I recall, he worked in quite a large practice in the south west.
The conversation turned to the concept of ‘givers gain’: the idea that, if you help others, they will be highly predisposed to help you in return. Not out of a sense of obligation (though there will certainly be some of that), but rather because, by offering and delivering help first, you show that you are an inherently decent person and others like to work with such people.
At which point, the accountant pulled open one of his desk drawers and retrieved an A4 ledger which he opened. He showed me the two facing pages on which he recorded the value of the work that he had received from others, and the value of work he gave to others. His intention was to ensure that he did not pass to others work of a higher value than he received.
