A rising tide lifts all boats. It takes a village. These are two common phrases used to describe how something that benefits one may also benefit many.
It to our benefit that we share what we do with others. What we share benefits us because of feedback from peers we may receive. Sharing our work might lead to someone experiencing an AHA! moment that increases their know-how.
Ask yourself, what is really keeping you from sharing your mousetrap? Besides, there’s easier ways to steal ideas: Like zombies eating brains for example.
