Needs

Obviously we have physical needs, basic ones like food, water, sleep and such like, but far more interesting in my opinion, are emotional needs. Partly why they are more interesting is because they vary more between people. My sister says she needs to see new things, it's convenient that she gets to be a world traveler.
Here are a few of my needs:

• Intelligent, thought provoking, interesting conversation. If I don't get it every so often I think to much in my head (instead of outloud) and often it makes me depressed, and yet one good conversation can solve most of it.
• An engaging, physical, activity. Soccer, shoveling snow, and sometimes walks can all count. This is arguably a physical need, but sometimes I think it's partly mental too. 
• Social interaction. Not necessarily a lot, and the above conversations don't always count although if the above physical activity is done with people it might work. Usually it's something more fun based, and although it's better when I am the active participant I can just be an observer.
• A book. I get book deprived. When I don't have a satisfying book (or computer game, etc) that I can fall back on in my free moments I am actually less productive. This is because when I "take a break" and it's not satisfying then I just keep looking for other entertainment so that I will be satisfied and never accomplish anything.
• A productive/creative project. This can be blogging (usually not) painting, drawing, crowdsourcing, list making, documenting, writing, researching, and a bunch of other things. If I don't do anything like this I get restless, and grumpy.

These needs are definitely not as well defined as food, and sleep. I couldn't tell you how often I need them. Is it daily? weekly? biweekly? monthly? Sometimes I think it varies. When I was on my two year LDS mission when books were not an option, surprisingly (or more likely I was just blessed) I didn't really notice getting book deprived. But I did get conversation deprived on occasion. 

What are your needs?
