Use a re-usable water bottle

I try to use reusable water bottles as much as possible, and when I have other water bottles, I always use them multiple times and/or recycle them where possible or return them to the store for the deposit, so they can be reused again.
I do the same for coffee and tea, I try to use my reusable coffee cups as much as possible, so I don't have to throw away all these paper or plastic cups.
