We tend to think that the right idea, the solid concept, is the one we will suddenly feel inspired to act on. The flaw in that assumption is that it's based on the individual being subject to a mindset that could lead to inaction. A mindset that says, if i don't feel like doing anything with this idea, then its just not the one.
The problem with that way of thinking is our feelings. While we should factor how we feel about a burgeoning vision, our feelings can be further influenced by some good 'ole fashion research and development. When we take the time to flush out what seemed like a good idea, we honor the brainstorming process by letting it lead us to the right course of action. And some ideas, like the awesome date night one, is a no-brainer we need to move forward with A.S.A.P!
The point is, don't get caught up in the quagmire of new ideas, that you fail to act.
