I've been vegan for 15 years, and it turns out it makes a very big impact on the environment to eat fewer animal products, which cause more greenhouse gases than all of transportation combined.
It's kind of a rule of thumb for me to self-doubt going into any kind of project. I always think that I shouldn't be doing it and I don't know how to do it and I'm going to fail and that I fooled them. I always try to find a way out.
