The quote "Never give anything away for free—but sometimes it pays to oil the wheels a bit" from Diana Gabaldon's "An Echo in the Bone" speaks to the balance between generosity and strategy in life. It suggests that while one should not offer their resources or efforts without compensation, there are circumstances where making small concessions can facilitate smoother interactions or negotiations.

This idea highlights the importance of understanding when to be generous and when to hold firm. It's a nuanced approach to relationships and transactions, reminding us that sometimes a little investment in goodwill can yield significant returns, fostering stronger bonds and promoting harmony in various situations.
