More than Likely you left something on. Or your battery is just old. I've had this previous problem with my 2004 Ford Explorer, it worked great, started right up then we left it over night then went out there the next morning and it wouldn't start everytime we would turn the key it would click. Then we took the cables off of the battery and the alram started going off. We ended up having to buy a new battery
