When it comes to ideas it seems as though we have an idea filter in our brains that we use to sort out the ideas that we hear. Some ideas get caught in the filter and we just toss them out. We hear them and just flat out reject them.
Then there are the ideas that pass through our idea filter and we accept them and adopt them.
But regardless of whether we reject an idea or adopt an idea, ideas all start the same way. They start out as seeds. Someone says something or we hear or read something and an idea gets planted in our brain and very quickly we begin the process of running that idea through our filter and decide whether to accept or reject it by asking the question: So Now What?
