Use a re-usable water bottle

I received a hydroflask and didn't realize how important this gift was. After reading about all the waste that plastic water bottles produce, my hydroflask is the only water bottle I have used in months. Things that help me are getting into a habit of bringing it with me everywhere and decorating it with stickers that make it personalized to me. I've had multiple people ask me about mine and it is one of the best gifts I have ever received.
