Meat substitutes taste great, you can still have that cheeseburger with something like beyond meat. Yes I'm biased but seriously give it a try. As for porn, I wouldn't even put it in the same ballpark as eating meat (if you're watching some free porn somewhere your contribution to the industry is negligent) , but anyways it might be overwhelming to try to change everything at once so I wouldn't even try. Pick one thing and commit to it. Maybe after that you'll pick another thing - and maybe not. None of us is perfect.
