People who are especially talented in the Input theme have a craving to know more. Often they like to collect and archive all kinds of information. This theme is a part of the Strategic Thinking Domain. Having access to resources give a person with Input the ability to think productively.
My husband has Input. He saves all kinds of things. Most of the time, he saves them ... not for himself, but just in case someone else needs them! To me, they are random collections of information, things and ideas. To him, he is building resources so he can give them away.
Just like a sponge, a person with Input takes in things and ideas in order to give them away. They are generous people with a love to learning and investigating!
