Some people try veganism but then kind of give up if they find that they unintentionally eat animal products or are too weak-willed
Whenever I hear this I can't help but think that the person is searching for the label "vegan" and wants that to be their label, rather than searching for acting ethically, and the label for a person that does so is "vegan". In other words, some label isn't the goal. The goal is to not hurt people and animals.
If you are still chasing a label and aren't motivated by reducing harm for its own sake, watch this in its entirety.
