I don't worry about my water, and from the research I've read, hydration IS important, but we can get our liquids in many forms -- including the food we eat. I think that sometimes we tend to overemphasize water AS water for hydration's sake.
Now, some people love drinking water! It makes them feel full, or keeps them from eating, or they just like it. That's great!
But if you're worried about trying to get more in because you think you "have" to, I don't think you should worry too much.
Here are some links that talk about the fact that the notion we need eight 8-ounce glasses of water a day (or more) is a myth.
This one is a link to a report of research by Dartmouth physicians

He concludes: "The universal advice that has made guzzling water a national pastime is more urban myth than medical dogma and appears to lack scientific proof, he found."
The original published research report is found at the bottom of that link. I should add that they note that their research "is limited to healthy adults in a temperate climate leading a largely sedentary existence". You do need to drink more when you get overheated.
And snopes is on board:

They conclude: "The best general advice (keeping in mind there are always exceptions) is to rely upon your normal senses. If you feel thirsty, drink. If you don't feel thirsty, don't drink unless you want to.
