You don’t need something ever. Sometimes you just want something because the alternative is realy bad. I don’t need to eat. I want to eat because I don’t want to starve.

I want to watch a movie with my partner at the agrees time because otherwise they will be mad. I want to access my digitalized documents to send a letter in time because otherwise I will have to pay late fees. I want to access my gameserver because that’s the one time a week I get to have fun with my friends from my college time.

There are many situations where I’d rather do the thing I want instead of doing maintenance.
