You decided to go vegan because you felt this is consistent with your values and standards. But your values and standards are not likely to be the same as those of every other vegan. The better you understand exactly what your vegan values are, and the more defined your standards of behaviour are, the more likely you are to succeed. Clarity of values and standards are key to success in any area of life.
You are likely to find it useful writing down your values and putting them in order. Develop a hierarchy of your values. Think about which ones relate to your veganism and which ones are independent of it. For example: you may value success, loyalty, adventure, fairness, health, learning, animal rights, social connection, and contribution. Put those in order. Which of those is most important to you? If you had to make a decision between doing something adventurous and something educational, which would you choose? Which of them relate to your veganism (in your mind)? There are no correct and incorrect answers. The exercise is just to help you clarify your beliefs.
What standards do you hold yourself to? If one of your values is health, what are the standards you hold yourself to, in order to feel you are consistent with that value? Some people may hold themselves to a standard that says, “because I value health, I never eat more than 20 doughnuts a day!” Another person may hold themselves to a standard that says, “because I value health, I run ten miles every day.”
Note that neither of those last two examples relating to health have anything to do with veganism, yet many vegans are vegans primarily for their health. For example, another person may have a standard that says, “because I value health, I follow a strict vegan diet.”
The clearer you are on your values and the standards you hold yourself to, the more successful you will be in anything you pursue in life, including veganism.
