One lesson that can be taken from "The Swallow and the Pumpkinseed" and the phrase "don't count your chickens before they hatch" is the importance of not becoming too overconfident about a situation or outcome. Both the story and the saying emphasize that we should not assume a positive outcome before it actually happens, as things may not always go as planned. It teaches us to remain humble, patient, and realistic in our expectations, and to not take anything for granted.
