What else can I do?

So I'm working on being a vegan me (which has been going really well so far, better than any other attempt! I have been 4 months meat free, mostly dairy/egg free, and very much strictly vegan in the last two months.  I got the idea to "ease into it" after realizing how much of a failure my previous attempts had been, and this is clearly what works best for me).  But I've been poking around on the internet (the result of too much time on my hands) and I've been thinking about trying to incorporate more ways to be less environmentally intrusive.  But it's also about saving money, simplifying things, and having less STUFF.  I have a lot of stuff. A lot. And I need to pare down.
