Unsustainable habits

I don't purchase the reusable bags for grocery stores and I use the plastic bags I always forget my reusable cup when I go to get coffee and my reusable straw My apartments don't have a recycling program so a lot of our cardboard boxes and plastic bottles just end up in the landfill and as much as I try bring it somewhere else its too much to bring on a trip so a lot of it ends up being thrown away so something I used to do was dumping all my stuff in the recycling because I figured they would sort it out later but I realized that just contaminates it and makes it harder to actually recycle what's in there so I stopped doing it since I still take notes on paper There are times where I wanna go grocery shopping after class or after work and I don't have my bag in my car and rather than going and getting a plastic bag or paper bag I drive all the way home and back to the store with my bag just for the zero waste part but I feel like it is actually worse for the planet because I drive past the store and drive all the way back sometimes I take too long of showers like 20 minutes, 30 minutes, an hour I use plastic bottles instead of reusable ones
