Well before becoming vegan you need to
1. Develop an undeserved self sense of superiority
2. Lean to the left on all political matters
3. Buy new clothes because you will be dangerously thin (or most likely already are)
4. ???
5. Follow vegan gains so you can get an idea of what an emaciated vegan weightlifter looks like
6. Definitely no profit
7. You are now vegan
