Here's a new life tip. Buy frozen fruits.
I use them for:
1. Cereal. Just take them out the freezer, plop a few in, and bam. Your cereal stays cold/refreshing, and you have instant fruit. Once you get used to cereal with lots of fruit, just cereal sucks.
2. Shakes. Like fruit shakes or protein shakes. Easy and makes it cold, don't even need icecubes.
