Dear Eric: I recently left a members-only business network group to which I belonged for half of my professional life. I was always a very active member of the group. Every year, I consistently gave many more client referrals than I received. I was happy overall with the business sent my way, so I kept renewing my membership and didn’t complain about the unbalanced ledger. Plus, I believe that it is better to err on the side of generosity. I had good long-term relationships with everyone, whether we did business together or not, we knew each other’s spouses and sometimes entertained the group in our homes.
