For a long time now I have advocated the notion that to get something back, you first need to put something in. Time, effort, knowledge, care, whatever. What you put in is less important that that simple act of being generous, and contributing.
It has always seemed to work for me, although the effort to get momentum going has often led to a few moments when I wonder if there is really a return on the effort.
What I have realised is that the crucial element of success is how, and to whom you make the offer.
Assisting those who want your assistance is not as effective as offering it to those who deserve it.
Wanting has become an expectation that something will just arrive, no cost, no obligation, whereas “deserve” inherently acknowledges a moral debt, and that your generosity will at some point be repaid.
